Lol, if quarians were the master race then mass effect wouldn't have had Shepard a human. Not to mention they would've been smart enough to not be exiled by their own creations but that's clearly not the case. Humans ended up deciding the council's fate, creating an army and ultimately stopping the reaper cycle. Humans>all. Crappy lifespan but what they lack in lifespan they make up for being all every other species isn't.
Humans have the grossly unfair advantage of getting to write the story, so they count about as much as Hitler's opinions on the untermensch in Mein Kampf.
So, the obvious Mary Sues and Marty Stus attempting to big themselves up via inexplicable writer fiat out of the way, lets ask an unbiased in setting observer in Harbinger. He's seen these cycles countless times before and knows what's what when picking who is gonna make the best, most flavorful new Reaper slushie.
“Quarian; considered due to cybernetic augmentation, weakened immune system too debilitating.”
“Drell; useless, insufficient numbers.”
“Asari; reliance upon alien species for reproduction shows genetic weakness.”
“Salarian; insufficient lifespan, fragile genetic structure.”
“Geth; an annoyance, limited utility.”
“Krogan; sterilised race, potential wasted.”
“Turian; you are considered...too primitive.”
See, "considered" and the only contrived "problem" he could come up with against us is something that would have never happened were we not too intellectually endowed with superior technical and scientific abilities for our own good, and could be fixed within a couple generations or even a few years (once we reacquire control of our technologies) by getting back our planet anyway (which happens naturally without Reaper interference).
Look at those lesser species. "Useless", "genetically weak", "an annoyance, limited utility" (this is seriously the funniest one because it's sooo true), "wasted potential", "primitive". Damn right. You can't fix genetic weakness, annoyance, or naturally being primitives. All clearly inferior. It's canon. We're best
Human Master Race, tho.
But Quarians can always tag along because they have such sexy voices
You guys look most like us and make suitable bangin' partners, so you can stay around as the most preferred client race.
Meh. Not very convincing.
