I developed a WA that i think is pretty user friendly to PVPers, Tanks, and Fury DPS Warriors. This allows you to remove some clutter/action bars from your screen and have all your main abilities right in front of you with some added perks.
My WA includes:
1. Weapon swing timer
2. Rage bar with number of rage shown
3. Rotation abilities which change based off spec ( Bloodthirst/Mortal Strike) (Death Wish/ Sweeping Strikes) and Overpower/Revenge based on stance, and Last Stand/Blood fury configs.
4. Cooldowns of abilities clearly shown
5. Cleave/HS Que clearly shown.
6. Battle Shout icon WA with time remaining
Upcoming:
Fury-prot spell customization.
