The Kennen Change on PBE

Just wanna say, that's the Kennen change I never knew I wanted. I don't main Kennen in any way, but this is his new change:

Slicing Malestrom (R) few changes - damage is similar for a full duration R but upfront damage nerfed significantly. Damage lowered to 40/75/110 from 80/145/210 AP Ratio lowered to 20% from 40% [new effect] "Successive maelstrom hits against the same enemy deal an additional 10% damage for each hit they've already suffered from this storm." [removed] "Each time an enemy is struck, further hits deal 25% less damage (minimum of 50% damage)."

I think it might be a little too much of a nerf, the the general concept of the change is there.

Reward Kennen for keeping enemies in his ult, don't hinder him for doing it.
