I'm getting a lot of mixed messages about this ability. I've got people on one side of me saying I need to use it before every lava burst when it's off CD, or that you need to use it before flame shock to improve it's overall damage...
What are your thoughts about this spell? is it a waste of a GCD for an elemental shaman? What about as restoration? Its it worth it when you are trying to eek out every bit of healing per point of mana?
