Zac E [Gameplay]
There seems to be a bug with Zac's E that I've been noticing over the past few months. When attempting to cast E, it will sometimes face a completely different, random direction from where your cursor is hovering.
I'm not sure if maybe it happens because the focal point of the mouse-over casting isn't quite centered on him, but it can be quite frustrating in any case. I have not found a way to reproduce this bug either.
Anyway, I hope this gets fixed sometime in the near future because Zac is one of my favorite champions.
Thanks!
