I was going off what I had heard others say.
On another note, Frost mage is a lot better than people think. I out DPS fire mages all the time on bosses. To take into account though, I must play Frost very well and I may have run into all "not so good" Fire mages. People complain Frost sucks on trash, I beg to differ. I pick the highest health not main focus target and Frost bomb it and change target as necessary. Single target and being a Troll is so badass too. Also, Frost mage gets a reputation buff so getting rep with the 6 factions is a little bit faster too. I'm 835 and the more haste I get the better it'll get.
