Look, Zoe's w should either give her a speed boost or damage but not both

After playing zoe ever since her release, she is a champion that i enjoy to play. But she is very over powered in terms of her W. I find it hilariously bad when I can miss all of my abilites but still destroy someone from 100-0 because i used my w. IMO the damage on it shouldn't even exist while her movement speed should be tuned down. It's stupid that zoe can miss all of her abilities but still be rewarded with a kill because of her overpowered w.
