Give Zoe's W a cooldown or rework it or remove it from the game

It's just that simple. Summoner spells are supposed to be important resources, her W is the most game breaking part of her kit. No champion should be allowed to use 3-6 or even more summoner spells within the space of a 10-25 second team fight. On top of the additional spells she has at her disposal, she has the potential to have infinite mobility due to the amount of movement speed she gains on top of flash mobility and all the other resources that she picks up from her passive bubbles.

If you're gonna comment about the fact that she basically doesn't have a second ability unless she picks up spells, keep that to yourself, the champion already has so much power in the rest of her kit and giving her a cooldown window between stolen spell uses would bring her in line with everyone else.
