i have yet to do extensive testing of either, as i've just begun to master the cold flare/hot flare rotation. But every time i've tried to do it in a real world setting (brayflox HM) stuff has died too fast for me to get to the 4th flare. Not necessarily because of my DPS, but because of the other DPS/WHM holys doing their thing too. And all of my recent T4 farms have been with 5 dps and 1 healer. I need to find some sucky DPS to run with so I can have enough time to properly test this rotation in real life.
