As for removing EGO powers, they are actually fine save Cloak. If Cloak added a shimmer effect when players are walking/running then it would make it entirely balanced. Again, this would have limited (zero?) impact on PvE. As a result, nerfing can be done without affecting PvE but it needs to be done properly; therefore such actions would entirely invalidate your previous statements.
EDIT: Also, reducing the stats of the Infector's bugs would also have limited effect on PvE as mobs do not even try to shoot them or run away from them. Certainly you must realize by now that there are plenty of potential ways to balance Infectors that would not affect PvE.
