I tend to open in a different order, open with quelling for secuirty reasons, 3-in-1 macro (ME/BL/SS) which fires off bloodletter to put it on CD, then fires SS, use raging, wind,flaming + IR, ven bite, hawks, heavy, B4B, heavy/proc, barrage, heavy/proc, continue with BL/HS/procs until 5sec left on wind, SS reapply, put back up DOTs, resume usual spamming skills, and keep working CDs as they come up to keep DPS level through the fight. Tend to save my invig for a specificl point too, once you reach 500-540 TP so its back up once i reach a critical low again.
