While i'll admit, shaco has seen some rough times...
I find him fun to play, and to be honest, quite balanced. Sure, he can't pop people instantly, but that's cause that isn't really shaco! Sure, he's an assassin, but he likes to mess with the enemies head, but in order to do that it takes time, and just bursting someone instantly takes little to no time on other assassins. not to mention most of the burstiest assassins all have their main damage into one ability(if you'd like examples, feel free to ask!) while shaco has his power spread through his kit, which is good! his q, though it does no damage it now reduces it's cool down and has a nice stealth duration at max rank allowing him to actually escape after a gank goes wrong. his W, even on ad shaco has tons of utility, escape routes, traps, it helps gank as well, with the fear. his E allows him to stick to his enemies, and his ult allows for more mind games, and can offer quite some damage if used correctly. I'd rather not riot buff shaco, only to overbuff him and proceed to nerf him in an area that was fine. Your thoughts?
