The only change that ryze actually needs.
These nerfs on PBE are way overboard. The only change he needs is either
Rune prison CD 14 seconds at all ranks 25/22/19/16/13 because by the time he gets perma root people will either have
or be tanky enough to survive his burst or be a squishy that deserves to die.
That or put a debuff on a recently snared target that makes them un-snarable but still take damage from rune prison.
The only overwhelming thing about ryze is his perma root. His e, ult, and passive are fine.
