I would like to say, you need a little bit bigger of a selection of firearms. The smgs could use a new weapon or two, same with heavy weapons and snipers. Snipers could use a new auto sniper aswell, maybe even a late game heavy sniper? It would just make the weapon pool a bit more interesting (stuff like the Mac-10, Double Barrel Shotgun, .50 Cal Sniper, M249 LMG, could use an SVD/Dragonov for the terrorist side for their auto sniper and keep the M110 as a CT weapon.)
