That doesn't explain how everything on Thessia is Biotic. Or how the Asari never noticed their Gods looked like Protheans Or why the Protheans didn't interfere with Humanity etc. Basically Javik shits on the lore big style.
Anyway, another big issue with the Asari is just how few of them there are - I think around 6 Billion or so if you add up all the planet descriptions - for the oldest species in the galaxy, who live over a thousand and who can breed with anything for centuries.
6 Billion? Yeah right.
As I said, every species (except maybe the humans) suffer from bad writing.
There should be at least 100 billion Asari in the galaxy, just from being the suspiciously attractive dominant species that can mate with anything that has a pulse advanced nervous system and controlling a dozen worlds. A planet like Earth can support ~10 billion people at our current technology level. With ME tech, we could go up to 20. The Asari control how many garden worlds? 8? 9? How many space ships, stations and colony outposts do they have? What about the Asari living on other species' planets? Someone dropped the ball here... there should be Asari everywhere.
Although then people would realize that the entire Asari species is as doomed. Why? Because they do not evolve anymore. Their method of reproduction circumvents all evolutionary processes in favour of a random number generator.
Survival of the fittest? Nope. Parents don't pass their genes on, every asari child is conceived by rolling dice on its stats. It doesn't matter if the mother was a famous huntress with extremely powerful biotics, the kid won't inherit it. The father never gets to pass anything on anyway, which makes finding a mate pointless from an evolutionary point of view. Even better, if I take the description literal, then the genes already present get scrambled. Nothing new is added through mutation or gene recombination, so modern Asari are exactly the same as the ones 50.000 years ago. How did they even survive the first 38.000 years if pureblood Asari mating with each other inevitably leads to Ardat-Yakshi, who are addicted to killing... and are sterile? The entire species would have died out within a few millenia, long before they discovered space travel and other species.
Btw... when the Council needed an army against the Rachni, why did they have to uplift the Krogan? They already had the Salarians. Sure, they are individually weak and squishy, but their females can lay entire clutches of eggs, they mature extremely quickly, they absorb knowledge at an unreal rate and you could have a combat ready army within a few years. Place that project on Thessia and they'd be biotics, too. Zerg tactics with biotic commando Salarians. Boom, no more Rachni.
Krogan on the other hand don't grow up that quickly, they probably need 2-3 decades to get out of puberty (human puberty ends with ~23, until then you still grow/change). How did the Council manage to get the tribal Krogan living in an apocalyptic, nuclear wasteland shaped up into an army in time to defeat the Rachni? Seems implausible.
Even better... how did the Turians manage to stop the Krogan with the Genophage? The Krogan had almost won, they were already in orbit over Palaven. A genetic modification that alters birthrates is not something you can a. distribute to every Krogan in existence, especially not when they are in warships over your homeworld, and b. it's only going to make them mad. It doesn't impair their combat abilities at all.
This leads to the BS that is the genophage. Adjusting the birthrates from 1000 kids to single digits is an excellent idea... if you don't mind forcing your societal norms on an alien species who more or less developed to survive on a hostile world filled with other Krogan. But that's not what it does. Instead of fixing birth rates, only 1 in 1000 females is fertile. All the others bear dead children. (Why even allow gestation, Mordin?! Sadist.) So, a complete failure in all regards.
Compared to this mess (and hey, I could write about that for days), being a biotic of varying strength according to what the story needs isn't so bad, is it?
