Zoe - Sleep Duration
Yep. One of those. Why is it that the presumed method of dealing with Zoe is to avoid her E, however she can easily warp into you at point blank range and smash her E into your face? The sleep duration is, fundamentally, the problem here.
I have zero issues with any part of her kit, beyond the duration of the sleep. She already has basically no cooldowns, and her warp has fundamentally no cooldown. This means that she warps into your face, puts you to sleep, warps back... warps forward again because now she is throwing a star at you... you are still asleep.
She can completely unload her combo before her sleep wears off, and it is basically due to the fact that she can spam literally every skill she has as fast as she can hit the buttons - with a sleep that lasts longer than any of her cooldowns. (Except the cooldown for Sleep. Which she flings at you again a few seconds after you wake up.)
