if you read new mage talents proposed, Coldsnap is now for all mages.
Notice how all other talents are 'useful' to all specs of every other class.
I know its still useful for fire and arcane due to double ice, and this alone brings arcane and fire needed survivability along with ice barrier with every spec.
But just think This coldsnap could mean water elemental for all mages.
yes i know the mage talents are kinda poo compared to others, but we dnt no wat our base spells and the new 87 spell are going to be, so what do you think?
