My mage is fire specced, level 45. This is the first class I've played up to the mid-levels that really needs to back up and control the fight versus just bashing everything, and I could use some advice from the more experienced.
I can take up to 3 mobs as long as the fight is on my terms - that is, if I can stand back, poly one of them, start on another (it's nearly dead by the time they get to me), frost nova, AOE if necessary til #2 is down, kill #3, then go back to the sheep.
My problem is with quests where this kind of advance planning isn't possible - say I have to go upstairs in a building someplace, just for an example, let's call the place "Tanaris," and there's 3 mobs, let's just call them "pirates," in the room. Due to LOS I can't pull or hit any in advance. So I walk in the room, or get so close that they come out, frost nova, poly one, the other two are beating on me and FN is on cooldown, and even with an advance Gift of the Naaru and using ice block, it seems that no matter what I do I'm dead before I can get them down or get FN back.
I realize that frost is the control spec and the way to control mobs with fire is to kill them before they can hit you. But what do you do in these situations where that's just not possible? Is the only answer Abandon Quest, or am I missing something?
