This game is a power weapon festival. I constantly have to deal with RPGs, Hammers, Shotguns, Snipers, all sorts of magical super grenades and so on. We should have either kickbacks or power weapons. Having both is too much. I wish we could have a "NPW" playlist but it probably won't happen.
PWs are one of the few things that separate Uncharted multiplayer from other popular titles. Its kind of like having an objective on the map in all game modes.
If you hate getting killed by PWs, get them first. If you don't like using them because they are too difficult to get kills with, take them and waste the ammo. Guard it for a teammate. Just realize they are NEVER going away in standard TDM.
They have a done no-power-weapons Lab on Uncharted 2. I can't remember them doing one on U3 yet. Maybe you'll get your wish soon.
Power weapons can bring a team back into the fight if used correctly, i dont know about having the removed but there needs to be less. Maybe just like in Plunder and Team Objective.
