I use as an AoE pull : glpyhed HB, DnD,blood tap and then another BB. usually after that HB is back up. this glues most mobs to me in heroics and for the tough mobs I hit Deathchill while running in to pull that way the crit of HB is enough to glue even tough mobs to me. my full AoE rotation looks something like this : HB >DnD>BB>BT>BB>HB>BB>BB>Oblit. and if rime procs hit HB again.

usually the rotation stays fairly well in sync. I also use empower runeweapon when the rotation gets goofy.

cheers
