So what if, instead Irelia's passive...

Irelia's passive instead stacks based on the amount of time she's stricken with a cc? Right now, she's ridiculous. She has an amazingly powerful stun/slow, that is instead getting its damage nerfed when that's not the problem with her. Then there's her passive, which makes her impossible to peel especially with the upcoming changes to tenacity affecting knock ups.

So wouldn't it make more sense, and make her much less problematic if her passive only triggers off of cc affecting her, stacking up to x times?
