1: Take Xuen's (Melee DPS) challenge for the Celestial Blessings (Legendary) quest.
2: Wait for Wrathion to do his semi-circle AoE attack.
3: Stand in the general area behind Wrathion, but not inside the dust clouds before it hits.
EXPECTED RESULT: No damage taken due to not being in the dust clouds when the attack hits.
ACTUAL RESULT: Damage taken when the attack hits as if you were still in the dust clouds, even though you are not in them.
