Sylas
What the purpose of constantly nerfing Sylas when you're going to keep his absurdly high AP ratios? Why even nerf his passive to this extreme when its not even where majority of his damage is coming from? Sylas' kit has one of if not the highest AP ratios in the game that enables him to be such a menace, but instead of addressing that specific area you keep adding more arbitrary dampeners to make him less relevant like Aatrox. Its not even an attempt to balance him but to purposefully put him in the back burner for who knows how long.
What do you want Sylas to be at this point? He has a kit of an AP Bruiser but with Assassin and Magelike numbers. Its not even like his kit is entirely unfair or broken either, its purely his ratios. Now I love playing Sylas because of his mechanics but I can never for the life of me understand why something like his Q has a 1.2AP ratio on a ~3 second CD at max rank. I just dont get what direction you want him to take. He plays as if he revolves around his passive but "balanced" in a way that it's a nonfactor. Its really sad because I actually find his kit to be one of the better modern designed champs excluding the numbers.
