Well we killed it last night, I did it as Frost, I tried all 3 specs, but Fire and Arc seem to clunky and proc based, I did ok with 76K, I didn't try any pet freezes on him or frost orb, i did use frost bomb on the sparks and it seem to do better than all others. What I did was get a frost bomb on elegon and then proc the FFB, then as soon as the sparks spawned would put my frost bomb on the Sparks send my FFB and then proc another FFB and send it and the sparks were done. I held my frozen orb for 5th wave of adds and it helped on all of them. I used Frost Orb on the adds when we grouped up and such, so all in all Frost seem well enough to continue to play with.
I played very conservatively the entire fight and I should of used RoP, but didn't I will next time. The sweet spot is great as it stops you from having to move to much. Next week I will try to manage all my CD's and play for higher dps as I know have the mechanics down and understand what spec I will use.
