After i watched some of your videos Deadvulcano, and a 19 twink named Spam, is when I decided to make a Frost mage.
I love the uniqueness of the Frost mage because not very many people play them. Our CC is awesome even though I still need to GREATLY improve in that aspect. Last night we were running thorough tunnel with last flag, winning 2-0, and then our flag gets picked with 1 minute left. As i blink up the tunnel I have Freeze ready, and as I turn the corner I throw a Freeze all the way across the room freezing a rogue carrying our flag. He was already past the wall, but I froze him in his tracks. I went after him and Frostbolt crit him 550, froze him again with nova, Crit him for another 550, and then 200 with Fireblast. We won that game. Oh yeah, I crit hard and often and make hunters wanna cry...
I recently played my first arena, and I realized how powerful poly is, gamechanging really. I freeze dpsers that attack my healer, and we basically own. Disc Priest+Frost mage+whatever, is amazing.
Also Like youakim said. If they move poly up higher then I might CONSIDER stopping, but I love my mage.. MAGES NEED POLY!
