In an attempt to leave leecher status i found something very useful, currently i run holy pala/disc priest/dk/rogue/arcane mage in 5s and i noticed that if you spec into Incanters Absorption you get rediculous pom pyro crits. Basically you have the priest throw up Power word: shield, Paladin uses Sacred Shield, mage uses mana shield, mage charges in(usually target a shaman) and then have the priest Pain suppresion, i usually get non crit pom pyros for around 9-10k and upwards of 15k crits. This is how I SZ JT(number 1 ranked 5v5 in the world)got so high up. Basically they just buff the mages damage.
