Will be running with the same setup we use for 10man ToGC runs.
Tanks: Warrior (Prot/Prot), Druid (Feral/Feral/Cat/Tree)
DPS: Paladin (Retri/Holy), Hunter (Suv/BM), Shaman (Enh/Resto*Swaps resto, frees up Ele shammy if ranged is needed), Warrior (Fury/Arms), DK (Frost/Blood). *Would replace the Warrior for a rogue but meh*
Healers: Paladin (Holy), Shaman (Resto/Ele*6th dps if 2 healers), Druid (resto) *Druid ain't always there so running with Priest (Disc/Holy)*
We chose to use a melee based team simply cos there's not a lot of waste buffs. Though low on ranged dps can hurt us at times I agree but works out just fine for ToGC runs and we got options to use incase we need more ranged.
