Senna's E isn't the same as an AoE Akali Shroud Vlad pool like so many people seem to think. Everyone in the shroud is still there in the shroud and will lose the benefit if they get hit. It breaks on a skillshot, it's not as broken as you want to think.
They can attack while in it, but if you leave her Shroud you are untargetable for a brief time (until you attack or get too close)
Every part of her kit is going to be whined about and anything that is even remotely strong will be held up as "proof. I was right shes broken rito so stupid wtf grabage game"
Meanwhile the win% on everything are pretty impressively inline and a majority of champs have viability in the majority of the game.
Edit. The same holds true for underpowered.
It's like your twitch if you leave the shroud or perma twitch while in the shroud.
