Played around in some BGs last night and after a few, I kind of like the aoe. Really nice for melee that's on you... I play boomkin/4 ele in bgs so magma x4 + starfall + earthquake x4 + hurricane (glyphed to reduce movement speed as well) > bladestorm, blood boil, etc.

Do I think it's a good AOE vs. ranged? Not in the least. But it's very effective against melee circle dancers combined with some of our other skills.
