I've always thought stickies were a little silly in this game, I don't they just started being ridiculous(my opinion). As far as PvP goes, I think they just have too much going for them. Magnetism and a 1hko allow for little counterplay imo. If you see a guy and are "close enough" you get a freebie. I personally think their damage should be brought in line with the tripmine, enough to prime, but not enough to kill.
