Need some opinions:

I got a 70 decently geared pally that I multibox with 4 elemental shamans that are now 69, 70 tonight.
I also got a 70 mage with tailored / instance gear (on the same account as the pally).

For 70-80 I plan to do as much instances as I can get away with, and questing for the rest - all 5 at once. I'm in no super hurry as my schedule don't really allow raiding anyways.

Question:
- Would it be beneficial to replace one shaman with a mage?

CONS:
- Haven't boxed with mage, so would take some setting up
- Looses a ankh, a heal and a set of totems
- I bet character transfer would be down if I tried transing to :P

PROS:
- Higher dps (?!?)
- Ports
- Summoned water/food
- Another CC (I think the shaman CC is a 80 spell, isn't it?)

I suppose I do think that the mage would be easier to solo level once the team is 80, and a 70 shaman probably never would get solo leveled with 3 80 shamans sitting around - So using the mage pretty much means retiring one of the shamans.

I think I'm fairly set on doing the 4 shamans, but looking for advice and input here

cheers!
