Ryze does not need a targetted cc ability with the amount of damage he can dish out.
Besides the fact that it's a pet peeve of him, Ryze's Rune Prison offers absolutely no counter-play when you play a melee. He already does a unhealthy amount of the damage, the least Riot could do is make him earn the snare by making it a skillshot (or removing/reworking it, whatever works)
Thoughts?
