Yes quad ret+x should be really strong imo, the new setbonus cuts cc duration in half when wings are up and hand of freedom+liberator+protector of the innocent or battle healer glyph is really strong for multiboxing, fear won't be much of a pain with that stuff, perhaps that team can be played again similar to kromtor's style going for high pressure instead of trying to oneshot. Perhaps use quad ret +enh shaman for snare, tremor and storm elemental with primal elementalist for 100% movement speed increase on team.

Though there is probably a oneshot button potential, final verdict actually does more damage than stormblast, pure holy damage with mastery increasing its damage and attunement: mastery, wings up, thats gonna hit hard, 10yard range is ok.
