This is how I speced in 2on2 with a rouge mate! We got to 1930ish in the best week.

This would be a solid spec if your planing to do 5on5.
In my opinion there is no "the best Spec" right now. Every Priest is doing it different. But
pain suppresion will save ur life trust me. In 2on2 as in 5on5.
Btw I can hold a 2k+ rating with some good friends right now.
We are 2 ms Warrior, 1 Heal Druid and 1 incredible undergeared Heal Schaman. We insta kill a clothie due to ms+decurseoftheirbuffsbecauseofmedispellingthem*lol*+windfury+bloodlust The fight then takes long but we got 3 healers so ... Win!
