Easy way to do that is just mouse click your macros instead of mashing buttons. That way your tank can get aggro while everyone else just chills. Moorabi is the first boss I downed with my 4 Dk, 1 druid team when they were severely undergeared. As long as you survive quake and can get your tank back up in health its easy. Now that snake boss is hell on melee only dps groups. The elemental boss that gave my shaman group a run for its money was pretty easy on my DKs. Of course the last boss is ridiculously hard with a melee only team.... ;(
