MF Nerfs...Why?

I know MF is considered "broken," but it's NOT because of her w or e...but yet you nerf those. I've been playing MF since before her new passive, and it's the ult upgrade and passive that make her so strong. The ult can get her back into the game, which is not her fault. Enemy teammates that get caught in the wrong position should have avoided it. It's not that op though, it goes for Malphite ult and brand ult as well. Nerfing her W and E just makes no sense as those abilities weren't that strong to begin with. C'mon guys stop this cycle of adding and taking away it just doesn't make sense.
