1 rogue/warr dps

Other recommended classes :

Enhancement Shaman ( to boost melee )
Elemental Shaman ( to boost casters )
1 another mage to make sheeping a bit easier

What do you need to know :
NO SLACKING ! Keep moving all the time and keep your eyes open!
Mage - if you have to sheep flamecasters - SPAM POLYMOPRH all the fight ( + spellsteal haste buff )
Every DPS member must do 1k+ DPS

Sorry for some mistakes in video and for bad quality of Zul'Jin fight.

Good luck and have fun !.
