building a mixed group atm

DK - tank
Ele sham - DPs and aoe heal when needed.
Mage - DPS
Boomkin - DPS
Holy pali - Main healer

Though Im not 5 boxing strickly as the Gf is running the DK leaving me using the pali as main with rest assisting nuke on tank. also lvling up a priest of my own so i can duel spec pali prot and solo when GF is busy.

havnt had much experiance of heavily mixed groups tbh Ive ran pali+4xsham at 70 for ages and tried a pali priest 3xlock which was ungodly at aoe! this ones more centered around doing harder heroics those i found impossible with CC on shaman at 70
