Ryze is an entry-level champion with the lowest winrate in entry-level games, but broken in proplay
Contrary to the memes, I don't think he actually needs another rework, at least not a full one.
He shouldn't be in the state he is, however. And a part of solving his issues needs to be addressing both levels of play -- weakening his impact in organized play while increasing his solo performance.
If you weren't aware, Ryze has some nerfs on the PBE meant to address these to an extent:
-Ultimate cooldown raised drastically -E base damage up early, the same late, and damage to secondary targets halved.
The change to E increases his early dueling power while weakening his waveclear, one of the components which makes him so strong at higher levels.
Changes like these are what should be looked at. Now, I don't think just wholesale weakening his wave clear in exchange for some minor buffs early is an equivalent trade, but it's the right idea.
Looking for discussion on what changes could be made for him from the community here. I'll put my personal thoughts later in the thread but just wanted to open the discussion first and foremost.
