Hey , I dont multibox, but i hope in the next month or so i will have enough money for everything i need. So I am trying to figure out my class make-up. I want to go Pa/Pr/Pr/Pr/Pr. Im definately going that route. But what im stuck on is, Shadowpriests or Holynukers with some Disc damage talents.

Shadow:
Pros:
More damage
Slight healing with VE
Cons:
Cant heal
More spells, harder to control

Holy:
Pros:
Picked up some talents in holy so i can heal if need be
Pop renew on my pallatank that at 70 BASE (no spell dam or healing) would do 1k every 3sec
Smite away and wen i crit i get instant smite.
Cons:
Mana?

Just wondering whats the better choice, thanks all. Oh yeah, the pally I already have at 70 and he will be in raid gearz.
