2 Suggestions for changing the Ryse passive to be not a early game problem

First off it should only effect Q W and E not his ult's cooldown. This sustain should not be endless given that it is 25% spell vamp and that goes a long way.

The second is make it reduce his abilities cooldowns by 1/2/3 seconds at levels 1/8/15 instead of "the cooldown of overload". This will make it a clearly useful thing later in the game especially with 30% CDR making it so he can potentially chain root during his passive with it at level 15 but not during the early game to the point where ryze can chain root in lane.

Not saying this will make him perfect but it will allow this part of his kit to be kept which does make him have an on and off switch for his power which is overall good.
