This UI you can use for any character you have, weather it be leveling an alt, running operations, flashpoints or PvP. Everything has been layed out so that it is easy to locate while still leaving plenty of room to not look cluttered.
I like to keep everything central that is relative to Raids/PvP with the target frames and cast bars for ease of interupts. The operation frames are located with the party frames.
I use quickbar 1 and 2 as my main ability bars. Quickbar 3 is where i like to put the abilities i use less frequently (Adrenals/Relics/Medpacks). Quickbar 4 is for the mounts/buffs/out of combat abilities.
Bottom left of the screen i keep clear (besides been used for Voidstar and Nova's maps) as i use a parse whilst raiding.
- Realigned the UI by editing the XML for perfect alignment.
