The way I see it is that Crytek has all these skills, such as air stomp, sliding, kicking car to act as a barricade to prevent bullets or crush enemies, but the fast death rate(die from 2-3 shots) prevents players from utilizing these skills to maximum potential. I think in order players to utilized those skills more effectively is by allowing players to survive a little longer. For now, I feel like Crysis 2 tactical aspect is kind of weak and should be improved on in the near future, perhaps crysis 3 maybe. I also feel that the game has sort of wasted some of these useful skills when they should been been utilized more often in a game encourages players to be more tactical. Now, I know that people use maximum cloak, armor, and nanovision often, but that's just about it. Most folks would still play the game of running and gunning because of what Crysis 2 has turned out to be.
All of this is my personal opinion, so correct me if I'm wrong. Try to flame less : ).
