It's a good point about polish that I had also noticed. I think you could actually shorten the enemy HP bar and scoot the enmity bar into the right.

It's very valid feedback. While by itself this is not big deal, when you start making addons and changes all over the place regardless of existing graphics, or that don't fit then the UI starts to look shoddy. Every effort should be made to maintain a clean, crisp, polished UI.
