So in a lot of the posts I've seen concerning cataclysm fire everyone seems excited about the changes to fire aoe but disappointed in the single target rotation.
Living Bomb, Hot streak, Fireball.
Tonight in my raid I was popping my haste pot and pressed ctrl 4 instead of ctrl 5. And I casted Frostfirebolt. At first I was like "Shit...," but then my inline aura showed up with the dot and I was like "Oh damn!"
It gave me this idea of fire going to be using frostfire bolt on single target fights just to keep the dot up? I know they took the dot off fireball and frostfire bolt off the baseline abilities but someone recently datamined glyphs in the latest build and found this
Couple this with our redesigned mastery of flat dot increase...Glyph of Frostfire Bolt - Your Frostfire Bolt now deals 10% additional damage over 9 seconds, but no longer reduces the target's movement speed.
It's just a thought, feel free to flame
