Right now I am looking at:

Prot Pally
Enh Shaman x3
<insert fifth slot>

I was thinking of going shadow priest in the fifth slot. Ideally I would like to have some raid viable toons at 70 and a SP is always wanted on raids (along with shamans).

What is the overall opinion on the synergy of 3 shamans and 1 SP versus just rolling 4 shamans?

Granted, all shamans would make it pretty easy to handle keybindings while adding the SP is another layer of spell tracking.

Thoughts?

(1-20 is still damn painfull too)
