Remember that your CC spells will suffer from diminishing returns during this encounter so it really help if you switch Hex from the pet to any Champion that is freely damaging your raid. I used my Hex spell on the Hunter's pet to keep it off our healers/casters. The secondary roll is to provide a combination of spot heals and CC. The main roll of an Elemental Shaman in Faction Champions is to keep sustained dps on the raid's target.
