the m4 is the best all-around weapon, the AK is more powerfull and has more accurate 1-2 shot bursts but if you go up against 2 or 3 opponents at once you don't have much chance with the AK.
In my opinion the single biggest thing they could to to improve the game is to remove the AWP altogether.
- I agree about the hack fixes, i've been playing a lot over the past couple of weeks and I've seen dozens of hackers, some real blatant. Its worse than its ever been before.
