Zed damage adjustment
For me, I personally would like Zed's main source of damage to be in his E, and his Q to be more of a farming tool, instead of a hardcore bully. As a melee assassin, i think most of his damage should come from melee attacks and skills, and not from long ranged attacks. I understand he can E twice during his shadow moves, but most people should be able to get away from the second E. He already has an easy time farming under turret because of his passive, so I don't think it will hurt much if you make him a tiny bit weaker in lane. Besides, late game, the only way to stop him is zhonyas, and qss for the adc's, which reduce his q and his e damage, (but i believe his passive does magic damage).
tl;dr i think zed should take more risks poking as an assassin in lane by turning some of the power of q into his e.
etc the list goes on forever. Wave clear champs exist, and wave clearing AD champions are really easy to farm on.
