imo it's the perfect blend of minimalism and utility, and a thing of beauty if you see it in action
topleft is your own health/mana, with your pet's hp/mana at the corner.
right of that is your target's target, that displays a % of health when active.
right of that is your target, with % hp displayed, along with tapped/elite/class/race/name/level info. also displayed are all 16 buff and debuff slots. above the frame are combo points, and the corners contain partyleader/loot icons, and status/pvp icons.
for your party members, it displays name, level, class, and numeric hp/mp values. in the corners are their pet's hp bars and %hp values (visible only if they have a pet) to the right are debuffs, which flash if active. below are buffs.
now, everything but the hp/mp bars is transparent to be as unobtrusive as possible... the less vital the information is, the more transparent I made it. also, nothing is visible unless active.
finally, hp bars change color progressively as you/they take damage... along with the unit frame behind it (the grey rectangle that holds all info). and, when you or your party members get to 20% or below, the entire frame will flash red to warn you.
anyway.. I think it's perfect. everything I could ever want, and none of the extra bullshit I dont need. I'd recommend you give it a shot.. the screen doesnt do it justice.
