Level 70 Fury Warrior Solo: Zul, Reborn (Mythic difficulty) 

Strange... The center area should open up once you've killed the first two bosses and those around the outside (Zekvoz, Vectis, and Fetid Devourer).

Thanks, it's *mostly* just careful placement of action bars using Edit Mode, Shadowed Unit Frames for the player/target bars, Details for the meters, and a handful of custom Weak Auras.

is it somehow possible for you to send me the whole thing? I've been trying to make a slick one for a while but I just wasn't able to, and yours is perfect xd

I use Shadowed Unit Frames for the Player and Target bars, so I can tweak the health/buffs/debuffs more than the stock UI will allow.
