She looks cute, but at the same time looks "childish" just like they mention that on the character reveal page. If nobody plays this character I'm sure they will remove it from the game. Don't you worry. They are looking at the stats on their sides.
Well, lately in every single game I've played there's been a Zoe, so I'm pretty sure that she won't be removed from the game. Her abilities in general are pretty unique, and she could be a cool champion if they just turned the dmg down.
