I'm seriously struggling with my 5-box composition and if I should have:

Pally, moonkin x 3, resto shaman
-or-
Pally, moonkin x 2, mage, resto shaman
-or-
Pally, moonkin x 2, ele shaman, resto shaman (edit: combo added late)

That intellect buff sounds nice, and free food & ports would be very useful, but the complexity of another class could actually decrease DPS. Thoughts?
