I only use smoke when the LTARs are there, cause they are always hating on me. But sometimes I would use it to run away..when I know I am gonna die. But..bottom line is most of the time its the other person (The one I am shotting at.) that pops the smoke so he wont get shot at. But it doesnt work..and I kill them anyway. But when and if they do fix the smoke it wont alter the way I play.
