I feel like you are incapable to make sense.
Zero. Evidence. Makes plenty of sense to me.
But that sure is sweet of you.
It is stated numerous times that the Reapers are hibernated in Dark Space.
Indeed. Now, let's count the number of sources who make this claim with any knowledge whatsoever of what actually happens in darkspace.
And somehow, without evidance, you come up with "what if they don't?" and expect it to be a viable argument against the Ark theory.
Yes, because tens of thousands of years is a long time for cosmic mecha-Cthulhu "beyond your comprehension" to just sit on their asses when there's organic chaos that needs fixing.
Actually you even expect Bioware to make the Reapers do something that would harm ME:N's story.
It's a valid concern they'll need to address, especially if they decide to exploit Reaper tech to make the centuries-long hike to Andromeda. Hell, they'll need to address it if they do the wormhole thing. A billion years of observing the universe is a long time to not run into other wormholes.
This is so illogical I can't even be bothered to go on with this.
Who's belittling now?
If you (and the others) want to constantly cry about the Ark theory, conveniences, contrivances, ass pulls, retcons, lore breakings, abandoning the Milky Way, and want to tie the hands of the writers with your arbitrary and petty demands, then be my guest.

Aw, thanks chief. Folks were gonna do it anyway, but we appreciate your blessing.
