As for pwshield, wouldnt it be more mana efficient to just heal through the dmg. With five who cares about pushback. Holy priests have so many heals it wouldnt it be easier to just heal through the damage?

I just reread your initial post, Ualaa. You said you wanted offensive capability. Holy priests are probably only offensive in the sense that you can keep dpsers alive through just about anything. If you want to be able to attack groups i guess you have to take he shockadin. If you want to primarily heal, id pick the priests. They dont have plate or a shield but who can lock down all five simultaneously while theyre spamming aoe heals in an emergency.

Paladins are probably more versatile than priests because you can tank in av or switch to ret for more dps. But if healing is your goal i would do the priests.

I would not do druids simply because you already have them and it seems like you want to do something different. Switching specs might not be different enougn for you. If it was, you probably would have done that already.
