while tear gas does not lag the game, after X of it being thrown, the particle limit is reached and you no longer see blood, cars smoking or cars on fire, bullet trails and you don't even see smoke after some time
gas's price should be equal to molotov's price or grenade's price
however we all have to admit that nobody will buy tear gas after it has a price
+1 about what reaper said about m60 / m4
m60's cost should be higher than m4s - all this talk about m4 being overpowered is bs as 'every weapon is overpowered in the right hands' (look: wk)
