Nerf Sylas
This is not just "I hate that champ, nerf him" this is serious from the point of view to the whole game. Sylas has everything, he has a stun, he has crazy damage on spells, his 2 spells do damage 2 times, he has an escape, he heals himself and he can have literally any ult, this is not fair agains so many champions, I can stand many annoying champions, but he is too overpowered both in 1v1 and teamfights.
Diana's ultimate for example is pretty strong and she has 80 seconds cooldown, while Sylas only has 60 (both at the max level) I know he cant select the same champion for 200% of that champion's ult, but he is pretty strong even with just his 3 spells.
