Depends how lazy/chatty I am. If I'm lazy/chatty, its just Hurricane. Otherwise I might use Starfall/DoTs/Starsurge spam. Getting completely smashed by our guilds' DPS warrior's tanking offspec and our elemental shaman, though.
Usually I got with DoTs/Starsurge/hardcasts for 1-3 and Hurricane for 4+.
That's what I do too while trying to be in solar when using hurricane (seems stronger that way).
And as for QQ, I feel like for a big crowd of mobs solar hurricane + starfall is pretty damn strong, I'm usually way above our ele shammy (since his chain lightnining has a limit of affected targets as far as i know). However, for 3-4 mobs then yeah, he is usually stronger unless they have enough life to make our dots worth it. If dealing with 3-4 mobs with low health then yeah, I'm screwed.
