But my point was that a "normal skill" has a much higher AP scaling than 0.2. If I wanted to make it just like a normal skill, the current 80 + (15 x level) + (0.6 - 1.0 per ability power) would be fine. That's virtually the same as Sion at all stages of the game.

Also, the ultimate has been nerfed since what the other guy said. It's currently a weaker version of without the silence, but is global.

And I thought about making it his ultimate... but then he loses out on a skill. :(
