beat the pants off Blizzard DPS. B3 is better DPS than B1, but the extra second of cast time is a huge deal, if you end up having to stop a cast to move or get interrupted even once B3 is worse than casting B1)
Third PhaseA (Swiftcast/Quelling/Raging off CD) : Transpose > Quelling > Raging > Fire 1 > repeat Fire 1 until almost OOM, cast Fire 3 / Thunder 3 off procs over casting F1 > Swiftcast > Flare > go to Second Phase
Third PhaseB: (Swiftcast/Quelling/Raging on CD) : Transpose > Quelling > Raging > Fire 1 > repeat Fire 1 until almost OOM, cast Fire 3 / Thunder 3 off procs over casting F1 > go to Second Phase

I'm unclear about whether transposing is better than switching with B3/F3. I didn't have time to test in beta, but it seems like Transpose is off GCD, but I had trouble casting spells directly after and am unsure why

Like I said, this isn't finished and parts are clearly wrong. I'll finish it after I get to 50 and can test in game.
