This build seems to be a common one for raiding mages: 0/53/18 (http://www.wowhead.com/?talent=oZfVcoRhIhVubhstbIccocZ).
I'll see if I can get Flambe and Kyndi to hop in here and provide their thoughts so we can help all of our mages scorch, freeze, and blast their way to higher DPS.
That is correct, what'd you do, copy my Talent build? ;)
Start off with 2 scorches, then do a Living bomb, then Frostfire bolt until you get a Hot Streak proc, then cast 2 more Frostfire bolts and hit the instant cast Pryo at the end of the last Frostfirebolt. Then rinse and repeat while occasionally casting a scorch to keep the debuff up and when you cast the scorch follow it up with a Living bomb.
