Kayle needs rebalanced

Kayle right now has such a power spike at 11 that she is now a mid game champ rather than a late game carry. I believe that she should have the 11 and 16 abilities switched and the true damage on the waves returned. This would give her the attack speed and increased range at 11 instead of 16, but have true damage waves at 16 so shes like kassadin where she gets a power spike at 16. Right now she feels like a mid game champ where she starts dominating at 11 not 16. I feel like this would also weaken her enough mid game to not be a mid game champ and instaed be the late game monster she has been for 10 years (not including recently). What do you guys think.
