I get matched against **_ZOE_**, I get one shot like how you would from a nidalee mid in season 3 and 4. The high reward low risk "Plays" that kills your motivation to continue. I then get matched against a Kayn that goes Assassin. He is 2-4, presses w and q, that's 1200 damage dealt in 0.03 seconds which just happens to be enough to one shot me while I was 6-1. Seems totally legit. That game went from everyone stomping lane to no one being able to kill this Kayn because his w just wipes everyone off the face of earth.
All in all, instead of nerfing champions like heimerdinger, nerf champions that need to actually be nerfed which make the game not enjoyable for everyone else in the game.
