for one i think this should happen to the following weapons and classes:
intervention and barret are ALWAYS 1 hit kill the amount of times you get bull shit hit markers because of someone elses sponged connection cause there watching GILF porn is unbeliveable

m21 and wa2000 need alot more recoil adding because of there firing rate , there firing rate and recoil balance is stupid...barret and intervention have like triple the sway of the m21 ebr and wa2000 yet the later can fire extremely fast if you can press fast enough and its just stupid in comparison

shorguns:
only the rangers should be able to be wielded AKIMBO as the models are half the freaking the size of your character and if you saw these in real life..(im 6ft 3inches and there like hip hieght on me...) and the kick off of these is insane... if you had these akimbo in real life you WOULD need a **** shit load of plastic surgery after shotting a few times from them flying back and smashing your face inside out

handguns:
damage should be brought slightly up or the recoil brought slightly down as some of these you can do a full clip and a half in someone and yet no kill they simply turn around on medium sesativity and 1 shot you with a ump or some shit

assault rifles:
need more recoil / sway adding to them as some of these are insanely to accurate..only one i can agree with being okay is the AK which tey probably just drag n dropped form cod4

anything else you people think should be implemented please feel free to add them here, now keep inmind these are my honest opinions form daily play and seeing which is obviously the most unbalanced items/unfair advantages/disadvantages witnessed
