1. It seems to be the smallest in the game, which doesn't match her model, at all.
2. The floating makes figuring out exactly where her hit box is incredibly unclear.
3. Her actual hit box doesn't seem to be centered on her shadow, for god knows what reason why.
The old Kayle model suffered from this to some degree, but the new model is completely outside of what is acceptable. Playing heavily skill shot reliant champions against her is a nightmare, because you often bait yourself into following up on skill shots that you're absolutely certain are going to land and even visually clip her, but don't actually hit.
Clarity really needs to be added before the next patch.
