I have a green (in terms of instance experience) level 70 Mage. I spec'd him Fire, and levelled him as such with great success (I never died questing in outlands), cos I like to burn stuff ;-) ... and have full spellfire / spellstrike set together with some decent complimentary quest and crafted blues. He's ok.
One thing I REALLY need to do, however, is get into BM (there's a nice staff and shoulders there, as well as the enchanter specific recipes from being honored with the keepers).
My main problem is confidence - I haven't instanced much, and when I have, I've done ok - I even topped the damage for a heroic SP run .. twice. However, that's in a situation where my job is simple, sheep and nuke (why I love being a mage). My confidence in my abilities though don't stretch far enough to knowing what to do in BM .. everyone says the mage's job in BM is add control, and they're the best at it - but how can I do that as a fire mage.
I can easily see how frost would help for add control - it's self explanatory .. you slow them down, and when they come for you, you Blizz them into the ground. My fire spells are for the most part single target, and my AOE spells have burst capabilities at best.
So here I am - supposedly the best for the job - and no idea what would be involved for that job. I've run BM a few times on my DPS (fury) warrior - and there my job was also simple .. slice the rift keepers up till they die, so I don't even have any idea of what the situation is with the adds .. I normally left that to my 'lock buddy.
Thanks for the patience and understanding, you guys have helped in the past, and I'm sure you'll help this time ;-)
