That is a sad excuse to use. The Quraians new there would be damage. They knew what starting a fight would entail. So to claim they didn't outfit their ships with the best they could out of fear of them being damaged is stupid in the extreme. Seriously you need a better reason then that.
The Geth out matched the Quraians in every way shape and form. It was only the Quarian's ability to blind the geth did they gain the advantage. When the Reapers ended that advantage the Geth started slaughtering the Quarians.
Who said anything about the quarians not bringing the best they could? They brought everything they had. The Liveships and their dreadnought scale weaponry were both a military weapon and strategic (food production) resource to the quarians. They couldn't afford to lose even one of them without half their population starving to death, let alone all 3, fortunately without Reaper help the geth can't threaten them. In fact, if you choose to genocide the quarians, the reason they are defeated is because the Reaper upgraded geth find and target the Civilian ships including the Liveships (according to the "Battle of Rannoch" codex entry) because those ships start firing on the geth after the Reaper is destroyed, not knowing that the geth have been upgraded again (because no one on the ground tells them). Similarly, if the Reaper code is not upgraded, the quarians obliterate the entire geth fleet (your vaunted Dreadnoughts and all) quite easily by simply sniping them from the other side of the system, using Tikkun as a gravitational slingshot to arc shells at the geth fleet, which with their bandwith clogged with garbage data are unable to find and retaliate
Haha, no. That's not how it went down at all. The geth were being obliterated by the quarians and lost four entire solar systems twice as fast as Hitler was able to take France alone in WW2. The Migrant Fleet in ME3 is objectively superior to the non upgraded geth, that is not up for debate. So superior in fact that Legion/ VI states the geth lost intelligence they were being schlonged so badly, and their survival was dependant upon the Reapers. The quarians quite literally beat them stupid.
Even when the geth were given upgrades to counter the quarian technological advantage, it only temporarily forces the quarians into a defensive strategy, using guerilla tactics against an enemy that outnumbers them nearly 1000:1 in terms of manpower until they successfully take the geth's Reaper endowed advantage right back away. There is no "slaughter" per the codex:
"In an initial battle against the Reaper-upgraded geth ships, the quarians found their Heavy Fleet and a portion of the Patrol Fleet outmatched. To stave off defeat, the quarians retreated at FTL speeds to rally with the Civilian fleet on the far side of Rannoch's sun, Tikkun. Temporarily hidden, but with only minutes of advance warning should a geth scout spot them, the quarians planned counterattacks to disrupt the geth link with the Reapers. First preying on a damaged geth dreadnought, the quarians followed by sending strike teams to Rannoch's surface to destroy the Reaper that was transmitting improved software to geth forces."
The geth slaughter nothing without their Pinnochio code and without their enemy being lured out of concealment and into a trap by a potentially traitorous ally (Shepard), wherein victory is practically handed to them on a sliver platter through no ability of their own. The geth only outmatch the quarians (or any organic except possibly the Rachni or Krogan, for that matter) in one manner: numbers. Despite individual networked platforms being as dumb as or dumber than animals, they don't require rest, sleep or wages, don't physically cease to exist unless you destroy their servers and can work endlessly to build more of themselves and simply win via attrition no matter how many you reduce to scrap. From the wiki:
"In combat, geth units show little sense of self-preservation. As geth programs are functionally immortal, they place little value on platforms and will expend thousands of units to take an enemy position, which was commonly experienced by the quarians during the Morning War."
Geth subscribe to the Zapp Branigan school of military tactics. There are plenty of examples of this in game. Shep and Co. slaughter thousands of them and singlehandedly push them off of 5 planets in ME1's Geth Incursions sidequest. Then we have Kirrahe, Kaidan/Ashley and a small STG squad obliterate an entire firebase worth of toasters on Virmire. Later on Haestrom, it takes a massive geth force with both armor and air support a huge amount of time to take on a single squad of "a dozen" quarian marines and Tali armed only with small arms. Kal'Reegar alone holds off a force described as "platoon strength" and supported by an armoured vehicle for an inordinate amount of time (A Rifle platoon in the US military is 42-43 men depending on whether you are talking Army or Marines), and with support from a little 3 man squad can obliterate them. The toasters again apply the "massive waves of geth" tactic on the Alarei, but are again defeated easily with only a few casualties either by Shep/Tali retaking the ship or the quarians simply destroying it after a small squad of marines fails to make inroads against the zerg rush of several dozen platforms. When going to evac Admiral Koris in ME3, you can come upon quarian civilian maintenence worker Dorn'Hazt, whom despite having never held a gun in his life singlehandedly takes out a dozen or so toasters before bleeding out (their platforms litter the ground near him).
Actually, this is referenced in banter between resident toaster deactivation specialists Tali and Javik if you take them on the same mission. Paraphrased:
Javik: "Quarian! You've fought these machines before. What are their tactics?"
Tali: "The same tactic as always: more geth"
Javik: "As I suspected, synthetics lack creativity. They think everything can be solved by numbers alone".
They're useless except as easily replacable, expendable cannon fodder (much like the krogan). The only geth that seems halfway capable in a fight pre-Reaper code is the prototype platform that Legion uses, which is capable of networking enough geth together to think of something other than "zerg the enemy until they run out of bullets or are crushed under the weight of our scrap metal". Apparently, they can't produce these en masse, though, because if they could there'd obviously be no point in continuing with the old models which are less than mindless, vicious animals. Even a pack of animals are capable of overwhelming the armed human hunter, given the numbers, but that doesn't make them superior in any other way to the superior human species.
By contrast the quarians are known in military terms for their impressive tactical, strategic and cyberwarfare and other technological capablities, which enable them to punch far above their weight, and are put on full display in using a population which is less than a single Earth city like New York to destoy an empire of billions of geth networked platforms spanning 5 star systems. This skill is referenced on multiple occasions. From the ME3 description
"A flotilla of 50,000 craft holding over 17 million quarians, the Migrant Fleet is the largest array of spacefaring vessels in the known galaxy. It is a testament to the quarians' strategic skill that these numbers have not dropped significantly during recent battles. The fleet is now on the far side of the star from Rannoch, the better to cloak its movement from the geth."
Specialist Traynor: "I'm networking the quarian combat data into ours, they've got amazing technical coverage. They might even have the salarians beat for strategic processing capability".
Commander Shepard also focuses on this doctrinal acumen when questioned about what the quarians are bringing to the fight by Diana Allers. From the War Asset description of the Heavy Fleet: "Commander Shepard's interview with Diana Allers about the quarians portrayed them as a highly skilled war force. The confidence in their fighting ability increased the quarian Heavy Fleet's morale."
I can't find the actual interview (I guess very few people are smart enough to destroy the geth), but Shepard stress how the quarian campaign resulted in "very few casualties" for the quarians. Where is this supposed slaughter? The geth are capable of inflicting no such thing without either a trillion platforms or being handed technologies that they themselves were too stupid to invent. By contrast, everything the quarians bring to the table is due to their own ability. Without Reaper's saving their toaster brethren, they get scrapped all the same.
Just to add insult to injury, the maximum war asset score for the quarians is also superior at 875 vs the geth's 815. Objectively, and even with the geth "buliding their own future" by begging Shep to save them from the wrath of their creators, and shamelessly stealing Reaper tech, it is undeniable: Bucketheads> toasters.
GETH= Garbage at Everything Toasters and their Huggers. They're just machines, and machines can be broken.
Quarians did not surpass the Geth. They exploited a flaw in their radar system. This rendered all their ships blind. Unable to see the Quarians Ships attacking they couldn't properly defend themselves. Had they had windows on their ships this would be a problem. But they don't use windows.
LOL. Ignoring that this isn't how the geth weapon works at all (the technobabble indicates that it overwhelms their bandwidth, not that it breaks their optics), now the geth lost because they don't have windows? You are aware that Space Combat in the MEverse occurs at ranges from thousands to millions of kilometers far out of visual range, rule of cool cutsenes aside. Description of the Battle of Rannoch per the codex, version with Reaper meddling removed from the equation:
"After the quarians eliminated the Reaper, the geth's processing power dropped precipitously and their bandwidth became clogged with queries for new instructions. Quarian fighters reported the exact positions of geth ships so that the liveships could fire safely on the geth from the far side of Tikkun, using the star's gravity as a slingshot. The geth command-and-control network was now in tatters, their forces separated by vast distances. The quarians hunted them like animals. It was not a one-sided victory -- despite vast losses, the geth staged a tireless defense -- but it was final."
but you're telling me that if the geth had put windows on their ships that they'd be able to retaliate against the ships reducing them to scrap from half a solar system away? Does their fire control system consist of the Hubble Telescope with crosshairs scratched onto its mirrors or something?
