Yah, theoretically, the 70 hunter and priest would make good party mates for running behind the warrior up into at least the lvl60 dungeons and the smaller tbc groups, but I find the overhead of running two toons at once to be a drag after awhile. I could easily have the priest non-grouped with the warrior, but on follow for absolutely zero downtime, but I kinda like being out on the edge there. (Although I will admit that I've travelled the priest out to a tougher levelling spot to save the warrior ghost runs. heh)

I just recently upgraded to a nice quad core machine and have the juice to run these, I just need the additional monitors.
