Before you chime in with noob... I haven't really played my shaman since the talent change at the end of Cata.
But given the fact that lava blast crits without the help of flame shock, would it be better to use frost shock with a root instead.
I mean obviously its situational. If you've got free reign to open up the extra damage would be better, but i'm just thinking that in times where its 1v1 or youve got a melee all up in your biznass that you might be able to get better advantage of frozen power now.
I DID go through some of the 5.2 elemental threads... none of them were really addressing this specific question it though.
