omen and recount can be hidden when u r not in raid to have a more clear looking. i also seprate buffs, debuffs and some special consumable buffs such as missile barrage,hot steak into different bars next to the buff bars to make it clearer when u have debuffs or consumable buffs.
the main addons i used for this interface are xperl, bartender4, ebb(the buffb bar), fu bar, skinner, sexy map.
this UI also suitable for other classes by adding or removing some class addons
u can contact me for more details if u like this UI :P
