But , your fire mage is 512 ilvl and he's last.
Do you find it normal ? I mean 145k dps with a +50% dps buff at 511 ilvl is indee not good , mainly due to the fact that fire got overnerfed. It was already bad in 5.1 , and now its even worse.
And the worst thing about it , is that fire is apparently the best mage spec with frost atm , and it's still at the very bottom.
