This is my Protection Warrior Aura suite. It tracks rotational abilities, Shield Block duration and cooldown, offensive and defensive cooldowns and their durations, Shockwave's and Storm Bolt's cooldowns, Ignore Pain's current value, Demo Shout (with Booming Voice), Ravager, and Dragon Roar's cooldowns, and indicates when Revenge is free.
It also has auras to detect whenever Battle Shout is not active, if Victory Rush is available, Commanding Shout duration (yours in color, an ally's in greyscale), and a Rage Bar.
