Delegation Quest

A Video to show the fight for the quest Delegation which gives the first staff towards Dragonwrath, Tarecgosa's Rest.
Phase 1 - Just interrupt and kill all of the Harbinger of Flame.
Phase 2 - Tormented Protector will need to be tanked at the entrance portal. He casts entangling roots which does damage, but only dispel them AFTER he does his stomp. If you dispel them beforehand you will get knocked back an enormous distance and die. Once he does his stomp dispel them as soon as possible. Small treants will spawn periodically and act identically do the transition phase adds on Ragnaros: they must be killed before they reach the treant. Ranged should deal with them. At the end of this phase he becomes friendly and casts Blessed Defender of Nordrassil on the player on the quest.
Phase 3 - Volcanus will fixate on the player on the quest (who is transformed into a huge tree of life) so tanking will not be an issue. Use ALL DPS cooldowns and burn him down quickly. There are a few spells to avoid, so as always do NOT stand in the fire. Healers have to compete with constant raid damage.
