This WeakAura is made for the Lady Deathwhisper encounter in Icecrown Citadel. When you get Mind Controlled, it automatically unequips your weapon (and related slots) to reduce the danger to your raid, then re-equips your saved set once MC ends.
Requirement: you must enable the in-game Equipment Manager (Options → Interface → Features) and have 1 free equipment set slot available so the aura can save and use a set for auto re-equip.
