Hi, I've been playing frost for awhile but I want to change my talent. My frost DPS on normal SoO is around 150-180k. Dungeons are usually around 200k+ and my burst DPS on a target dummy is 300k. My ilvl is 540, I want to switch to fire but I hear it is very item dependent, however a good fire mage can have big DPS. So is it time to switch or should I stay at frost?
