Hm, an interesting idea - the mage buff and portals wouldn't be bad to add to the versatility. And, since I would still have 2 shammies, and I very rarely have ever needed more than 2 reincarnations before one reset, I guess losing that wouldn't hurt.

The resto shaman will be dpsing with LB in order to at least recover mana, and I'll mostly heal with an "Emergency!" macro for situations where I need it. They would definitely both be dual-specced in order to allow for maximum flexibility in situations where I don't need the healing; I tend to have issues in certain kinds of fights where the extra survivability would be nice to have.

Thanks - I think I will swap out the 2nd dps shammy for a mage and see how it works!
