If they redesigned most of the firefight arenas to allow for more flanking, made it easier for you to dodge enemy fire while sprinting and made it more fluid to go in and out of cover, the game's combat could be redesigned to allow for lower-HP enemies with the defense system in its present incarnation essentially gone.
It's not difficult to make enemies flank you, but if the enemies flanked you in the current iteration of the ME2 combat engine, you would get fracking slaughtered because they have such a ludicrously high amount of HP, and there is no way for you to effectively crowd-control them except on low difficulties (armor, shields etc prevent you from using CC like pull).
Personally, I would like custom difficulty selector, where there are sliding scales that control A.I. tactics, A.I. aim (i.e. how accurate they are generally), A.I. health, Player health. Then people could customize it to however they want. Then they can take out the friggen insanity achievement.
The AI in ME2 is very good

Can anyone point to a game that does this well. I mean crap tactic AIs seem to be the norm to me.
Not in cover shooters, but if you extend your net to FPS games F.E.A.R. is the king, followed by Crysis and the recent iterations of the Halo elites. The essential problem with cover shooters is that the static nature of a cover system (encouraging you to stop in one place to do your killing) makes it difficult to program A.I. that appears "clever", since getting flanked in those games is almost always a death sentance, so the A.I. is generally not very agressive.
On higher difficulties they just usually crank the A.I. HP and lower your HP, because it's easier than getting the A.I. to behave smarter.
