Hey we were talking about your build last night, I was looking up some of the other mages in our guild and most of them have pretty solid builds, so here's a few of them.

He gets a TON of power from arcane and that power goes to his frost spells (increased spellpower, arcane power, clearcasting ect.)

Hope these give you some ideas if you're looking to change up your spec.

One thing about frost is it's so super mana efficent anyways!  If you got any questions just lemme know!
