Yeah I think I'm going to tough it out with the Shamans.

I have a warrior and a priest I could use for boosting (not as good as a mage I know, I also have a 70 mage but she is horde and I'm alliance now) the warrior is 62, she seems like a better choice for boosting because of sweeping strikes + whirlwind will take out a bunch of low levels in one go. My problem is that I have 5x shamans how do I boost? Do I do 4 at the time and rotate one out? I did this last night, I grouped the 4 'clone' shamans with the warrior and a run thru deadmines got them almost a full level. I still need to learn to gauge how close I can get with the lowbies before they pull aggro that caused me a wipe last night, as the warrior can't res =)
