Counterstrike would be perfect if...

What do you think would make it or any fps better?

I'd like it if you could give control over your player to a dead player on the same team if you wanted to go afk.

This seems like a /v/ or maybe /g/ topic. I don't see why you posted it in /prog/.

I haven't played CS in ages, but I don't see that much of a point in the addition you want to make. A dead player died due to his mistakes, he should wait to respawn once the round is over, if you want to go afk, just become a spectator.
