Yo mate. I will hit 70 next week and go straight into arena to farm points. And i think that i will try out with a frost mage suporting my shammys rather then a healer..

Basicly my idea is that he will asap run straight into them.. and keep them frozen for as long as he manage, spam some arcain blasts and iceblock before he get killed. While i just stand on max range nuking them down...

Maybe you should try that out, might work
