Here is a link to our WOL parse from yesterday (everything killed except for Sindragosa + LK).

I was Arcane, as was Evilwillow; Moiste was Fireball specced. You can take a look through the damage reports to see how it performed for him.
For our kills (using overall damage) I did 0.94% more damage than he did, so about a 1% difference is really respectable.
The issue was that with fights that were DPS races, on Bloodqueen especially, I was the third person to be bit (Moist was first, who then bit Lerentis, and on the third bite I was picked), I ended up beating him in total damage for the entire fight (and that is with no IA, etc). My damage done is low (for me) on two fights: Rotface (picked 4 times with Mutated, most of anyone), and Princes as I am assigned to cover the entire front section's kinetic bombs to which I just use a mouseover ice lance macro most of the time...
Has fire become more competitive? Yes. Has it surpassed arcane? Not that I can tell. I may try fire next week for those same bosses to see how I do in comparison to take out the 'player' problem from it (although I haven't played fire since... umm... Ulduar/beginning of ToC?)
