I understand why Riot would want to remove the reworked Ryze from the game a la Urgot or Olaf in seasons past as he was suddenly seeing a ton of bans and some play, and albeit his win rate wasn't that stellar he had a really unhealthy kit.
His kit simply isn't in a healthy state right now, and that needs to be addressed before he sees play again, as I adress [here.](http://boards.na.leagueoflegends.com/en/c/gameplay-balance/oRhBxn5B-why-ryze-is-both-underpowered-and-broken-and-how-it-can-be-fixed)
Gutting him "fixed" the problem by making sure he doesn't see much play, but in-game he's still unfun to play against all while dragging down the rest of his team so they can't have any fun either.
We are nearing the last patch for worlds now; I hope riot decides to work on him now that they can do such without potentially disrupting the pro scene.
