basically, be sure to keep them perma-slowed, and only use AOE abilities in order to proc as much Spellweave procs as possible.
- all warriors: get Blood & Thunder, spread Rend, Heroic Leap, cleave as rage allows (prot: also use shockwave; arms: use sweeping strikes+TC+Cleave, pop Reck+Bladestorm on 2nd set of bloods, 3rd set repeat as 1st set)
- your rogue should just FoK spam (blade flurry? not sure if ours do that combo)
- priest mind searrrrrrrrrrrr, forget about dots (the GCDs to put any up would be wasted since they have to manually DOT)
- DK drop Death & Decay in the bloods' path (not on their spawn point), spread diseases immediately, then blood boil like mad
- retpally SoR, divine storm, holy wrath (pretty sure, just wowheaded some knowledge)
- hunter multishotmultishotmultishotmultishotmultishotmulti shotmultishot
You never go full Rickotron.
