Alliance UI...

That's a nice aesthetic design, but it's usefulness is subjective. To me, the bars are far to small to easily take in with a quick glance. The current design suits it's purpose, although the fat squat bar is horrible for telling health percentage etc so overhealing tends to occur a lot.

I would rather prefer them in list style similar to the current party bars, there's obviously no need for MP/TP (although having the option to display below HP is nice) and it can allow for 2-3 debuffs to be shown next to each health bar (health bars need to be extended, my preference would be almost double their current width). Finally I would like to be able to replace party bars with a raid bar for your group as well, I don't see the necessity for having unwieldy large frames in any party circumstance. I would PS the current bars to show how I would like them, but this is only subjective to my own opinion and I'm sure other people would disagree with it anyway.

I think the alliance UI is fine. Whenever they come out when addons people who want some kind of custom UI probably can get it then.
