What's the end all, be all, Arcane spec for all current raids. Current raids are all ToC's and lets say Ulduar for those that are still progressing through it.
It would be great to just have link to the spec and maybe a word or two as to why you chose it, but really, I want to end the IA, MA, Inceneration, AC, Frost Warding, etc... talent talk and make a decision on which spec gives you the most DPS. Mage's need to know how to survive and that's what healers are for. Mages are here to top DPS charts so survivability isn't a top priority in these specs (although a plus of course).
So what is it fellow mages?
