I've been talking about this a lot in different threads.

I am an elementalist: http://www.worldofwarcraft.com/info/classes/mage/talents.html?0000000000000000000000055523101000003105310510530321010005000000000

I have literally, in the last 6 hours, respecced four times, so if this one is different from other posts, it's not because I'm lying or anything.

My theory is such. For PvP, I usually start with a spell fake like poly or another arcane magic, unless I have the advantage of not being seen. I also have Combustion up ideally. My rotation usually follows (ideally): Rank 1 Frostbolt, Fireball, Scorch, Fireblast. Usually I can hit all three for a shatter crit with good timing. That's a lot of damage, as I am hovering at about +8xx fire damage and I have 2 pieces of the Aldor set (no interruptions). Of course, other complications arise: (frostbite never procs, fear- though I am normally out of range and I have WotF, etc.)

For groups of enemies I like to, of course, blink in and FN, Blast Wave and Cold Snap, FN, Dragon's Breath, Arcane Exp... With crowds though, stuns suck and fear too, although again WotF.

My question is... any elementalists have a better spec, or a better rotation, or any tips at all? I think that elementalists need to make a comeback, and I plan to stick with it except for raids, so any help would be nice.
