I started to level on fire, and reached 118, until I got to a dungeon where a frost mage lvl 113 was outputting easily 8k dps, compared to my hard earned 4k dps, talking about single target. Using a popular rotation from icyveins.
So I went Frost and things changed tremendeously. I could easily reach 8-9k dps.
So is Fire really that far behind Frost, or it is I that I haven't got a clue how to play Fire?
