So I've yet to decide what spec i'll be for cata dungeons. After watching most of "Totalbiscuit's" videos on you tube i think i might be fire for dungeons just due to the amount of AOE on the move you can do. Anyways, I notice in his vids he's mainly using Frost Fire Bolt again. Once I hit 81 and my crit starts scaling down again, would this be optimal with the glyph over the glyph of fire ball? I'm not a theory crafter but looking at both glyphs it's hard to decide. My mage isn't in crazy gear and I was testing both glyphs today as fire spec on the 80 dummy but with little results in difference.
Anyways, you're thoughts are appreciated!
