line-up Change

Currently I'm running a lvl 70 Human Prot Paladin with my 4 lvl 54 Dranei Ele Shamans. I have decided that it's time to shake things up a bit.
I have a lvl 50 Dranei BM Hunter and have decided to swap out that Pally for the Hunter once the Hunter Reaches the same lvl (54).
as the Hunter and Pally are on the same account I will be able to swap back in the pally, when I start running heroics.

has anyone had any experience running this kind of hunter/shammy setup, and are there any issues/tips I should be aware of?

thanks
