I think that they developed this mechanic to be done with 2 healer and 4 dps. Both MT and OT need to then share Fae light afterwards. I think this is the best one, since 2 healer and 4 dps can take the hit while DPSing, then TOP everybody with AoE heal, without needing to waste a GCD to heal every hit.
But all the strats are valid if they complete the fight.
