I setup my own for tanking because all the UI packs out there seem to be designed badly with action bars at the very bottom of the screen etc my UI is a similar to Kirparians on Youtube but looks a bit nicer and less cluttered but action bars are raised and HP bars either side of my character and omen above the target frame big debuffs etc
Infact i think there is a sticky on these forums explaining how a tank should setup there UI
