^Exactly my point. I find Combat Arms SOOO much easier than Counter-Strike, even if CS had bigger head hitboxes than Combat Arms. There are pros here and there but generally there are a lot of noobs and bunnyhoppers. Since jumping has no slowdown effect, they couple that with high movement gear and a shotgun. I could hardly do a thing because the game is laggy and unsmooth server-wise. Shots don't register all the time either. The majority of them are sprayers too. Ever since Nexon released the HK416, spraying became really popular since the HK had sooo little recoil all you had to do was scope in with an ACOG or reflex sight, pull down slightly, and spray away. All 4-5 shots needed to kill the oponent will hit. And the gun fires fast so you'd be dead in a second.
In CS, I find that a lot of people are quite fast and very accurate. The moment you turn a corner, you die. And they spray very accurately... with an AK-47.
