I think this games perk system is great in the sense that there is some form of progress to the game but i don't think they really capitalize on it. I suggesting that the tier 2 weapons and some others are limited to the class they go with. for example on a support character should be able to use the hunting shotgun, only sharpshooter can use Xbow, only firebug can use flamethrower, etc. because right now the perk system is just that you do more damage with a certain class of weapon or do something better than others. Other weapons such as the LAW, Dual 9mms, and Tier 1 weapons should be available to all classes. The medical syringe should also not heal as much when used on yourself since I rarely ever see any medics in a game and if i do its because they can run fast. the welding tool should stay the same since even lvl 5 support guys need help welding sometimes.
