The majority of my UI elements are hidden while I'm not in combat and/or don't have a target selected.This keeps down the clutter and lets me appreciate the game world a bit better.
Aside from the giant green minimap, the first thing you'll probably notice is that everything is clustered in the middle/bottom half of the screen. This is a deliberate design decision based on what I've observed about my own in/ability to readily see things located at various parts of the screen.The third image is an approximation of my screen viewing ability, with green being the most accessible and black/orange being completely inaccessible.
Eye dominance is the major factor here. I am left eye dominant. Centering on the middle of the screen effectively blacks out the far left side because I have only poor peripheral vision from my left eye, whereas my right eye contributes to a greater deal of awareness to the right half of the screen. The height/distance and overall positioning of my screen relative to my eyes also play a role in this.
UI Element Breakdown
Player/pet frames - I usually see the mana/power bar located directly underneath the player health bar on most UIs. I have instead replaced it with my pet's health bar, because I use a separate focus bar. This was done by adjusting anchor offsets on Shadowed unitFrames.
Target frames
Focus bar - Quite possibly the most important part of my UI. This bar is from IceHUD, There's a matching Alt.Power bar on the left side that shows up for things like Flamethrower heat...
Trap CDs - these are two small Power Auras that show up as stars when the trap is available, or displays the remaining cooldown (in seconds) when unavailable. Obviously, the blue star is for frost traps, and the orange star is for explosive trap.
Stunbreak CDs - Master's Call and Every Man for Himself (the human racial skill).
The wings are static artwork, though I also use them as the basis for certain triggers, such as the smaller set of wings in the combat screenshot (the small wings indicate that my Steady Focus buff is active, and will flash when about to expire.) The golden orb in the center was inspired by the Guild Wars 2 endurance bar. It empties when I use Disengage and fills back up while the skill is on cooldown. It also doubles as a range indicator (the text in the center of the orb).
This is an addon called MagicTargets2. It displays a list of all the targets currently targeted or engaged by the raid, and how many people are targeting each. The green triangle shows which one I have targeted. This is generally not very important, but comes in handy when I'm tabbing through multiple adds and allows me to tell at a glance if I'm attacking the right target.
