And Prothean data, Leviathan, etc. Lots of intel before the Star Child came around to visit.
What Prothean data? If you mean anything from Javik, that and the Leviathan are DLCs and therefore optional. Where is there intel in the main plot?
There is also no reason they would need to. The cat is out of the bag they hit the Batarians first creating the initial wave of ground troops then started in on other races converting them as needed. By every intelligent measure the galaxy should have been ready and waiting for them. Sadly not everyone is as smart as the Geth. So a convenient left alone with no ally race like the Batarian creates perfect front line troops.
There is no story reason for them to need to take the Citadel. They seem to be doing fairly well without it.
Yes, the galaxy should have been ready but that's a separate issue. The story reason for the Reapers to take the Citadel is because that's how the Cycle works. Vigil tells us all about it.
Citadel isn't needed to lock down all relays. The only thing so far shown the Citadel has the ability to shut down is the relays that connect to it. Which was something already known by the Council races. Other wise they would have shut down the Relays during the Rachnii Wars cutting them off. Opening them only long enough to send troops into the battle zones.
Vigil describes the Reapers shutting down the network to isolate the Prothean systems.
No the conventional victory would require the Reapers stubbornly sticking to the existing tactics while never adapting. Something in game they are shown to do. Meeting the Turians who fight with head on strength with even more strength. Learning the Asari hit and run moves and adding more troops to the point the hit and runs could no longer be maintained forcing them to create a defensive perimeter to the planet. Which because it wasn't how the Asari or their ships were build for they were run over by Reapers.
It would require such sacrifices it would pretty much be a Pyrrhic victory.
There is no such thing as a Pyrrhic Victory when the alternative is extinction.
Look if you want to bring realistic play into this series Shepard shouldn't have gotten to Ilos to start with. Sovergin should have been waiting at the relay an in orbit. Even if they got to the planet without trouble the second Joker air drops them in Sovereign should have found them and blew the hell out of Joker. No Joker then no human fleet. No human fleet then Sovergin would be free to sit there on the Citadel until he regained control without worry of any ship or ships shooting at him. Shep would have delayed his plan ever so slightly but ultimately Sovergin would have won and the Reapers would have appeared.
You do know why the Reapers blow up ships right? It really isn't because they want to. More because they need to destroy all defenses before they can start harvesting. Kind of the equivalent of swatting annoying flies before you start to BBQ outside. Destroying those fleets would make it so much easier to harvest planets with 90% of anything that could get in their way destroyed already.
Who said anything about being realistic? I'm questioning why the Reapers don't do what they've always done when it is not only within their power to do so, but is the smartest course of action. Yeah, Sovereign could have been guarding the exit relay from the Mu jump or guarding Ilos itself, but that can be handwaved. He didn't destroy the Normandy at Virmire. I just figure he dropped Saren on Ilos and then went to stage with the Geth fleet for the jump to the Citadel. You can say that's silly, but it doesn't violate a plot point.
And yet the Reapers always do the divide and conquer strategy, except for this cycle. Well I suppose it's nice to actually have them acknowledge that this cycle is different, though the Catalyst ignores it. Seriously though, the fact that they divide and conquer rather than herd the galaxy's forces together as you're describing was something that made me wonder if Sovereign was posturing and the Reapers, while powerful, weren't as invincible as he let on. Things Vigil says could support that as well. However it could just be that isolating systems lets them send fewer Reapers to each place and thus hit more places at once.
It also deals with multiple synthetic creations over thousands of years. You have 1 example over 200 years. Multiple examples over a long time period vs 1 example over short time period.
Oh but that is right AI never showed it's work. You know it is really odd how people choose to disable their suspension of belief. A single team is able to wade though enough corpses you could build another great wall out of them. No one bats an eye lash.
How ever an AI claims synthetics will create chaos and kill off organics. Even though this information is backed up by the decedents of the AI's creator. You know pointing out how dozens of Thrall species were killed off by their own synthetic creations. Because said AI didn't show his work. Everyone loses their mind.
My one example is the one relevant to the current cycle. The Catalyst makes claims but presents no data, forcing us to trust it as an authority. While the Catalyst may be right about the past, it is wrong here.
That Shepard and Co. can take out so many enemies is something we accept as viewers, or players in this case, of action media. It's common and is, in fact, something we expect going into the fiction. This is not comparable to a character being introduced at the ending spewing ideas that were at best not presented and were at worse countered by the story.
The Leviathan DLC is optional and is an argument after the fact. The main plot, not side content, needs to back up the Catalyst. It does not do so.
By the paragon route, the peace can also be forged because the geth side of the Morning War also comes out. Shepard can declare "the geth don't want to fight you"
Without the upgrades, I'd say that the liklihood of the geth 'enslaving" the quarians is close to zero. The quarians have nothing the geth want. And the geth themselves just want to become "whole" and while away the centuries in their megastructure calculating pi, or whatever. Picking the quarian home system to be where said megastructure is located was the writers forcing the geth to hold the Idiot Ball, though.
With the upgrades? The geth are now Real Boys and I guess don't need to be brought together. I guess the want to help the quarians get back on their feet. And then, who knows?
That's the tone of the writing, but I'm talking about what might be running through the minds of the Quarians.
However, I don't agree that the Catalyst could use the situation as an argument (apart from in regard to the "created will always rebel against their creators" part of its logic). The only Reason the geth can even survive to enslave their Creators is because of technology the Reapers gave them that is far more advanced than their own or anyone else's in the cycle. At the same time, the converse is not a counterargument to its logic though. The geth simply weren't advanced enough creations without Reaper tech, comparable to the rebellion of malfunctioning mechs Shepard & Co. put down at the Hahne-Kedar Facility in an ME2 sidequest, though obviously on a much larger scale. That they failed doesn't mean the cycle's species won't build more advanced ones that finish the job, as they always have.
It does use them. The ME3 Multiplayer has been described by developers as canon, and the Collectors are an enemy faction, said to have been brought in on "black arks". They seem to essentially serve as a sort of "special forces" under Harbinger in relation to the standard Reaper troops. There's even a playable "ally" Collector that is one of the Leviathan's thralls.
It's just a shame they weren't in the Singleplayer game considering they are a much greater gameplay challenge than they typical Reaper troops. Would have been cool if Priority: Earth had Harbinger specifically roll out the Collectors to try and stop Shepard & Co. (4th time's the charm?)
I meant the claim that the peace won't last, not it's initial premise for creating the Reapers.
Also, I know it was in reply to someone else, but the Collectors being in multiplayer was added later so I consider that an argument after the fact. It was shoved in to provide some more variety/ new content. However I must strongly disagree on their inclusion in the single player. They were silly in the last game and I didn't need more of them.
Destroy leaves too many unanswered issues for my tastes (eg; Krogan overpopulation); much prefer Synthesis.
How does Synthesis solve that problem? And you have no problem with forcing that massive change on the Galaxy?
