no I'm suggesting that at a certain point in game he might turn into something similiar like Saren
now don't get me wrong I know his implants are different but unless they want to make you fight the Illusive Man himself at one point, why would he need implants story-wise?
Edited:
I just wish that at one point he starts talking exactly like Sovereign
He has implants for multiple reasons, including the fact that he's old and trying to remain youthful for God knows how long, he's the head of a massive secret organization (where Implants could help with the job) and perhaps a tinge of irony (the head of the most Human-Centric organization is in fact barely Human at all.)
