Aye, I can see how a guardian druid would be best. But I don't have one of those - I'm boosting a druid lol.

Chain stuns can be a problem if you're not expecting them. I was once boosting using a prot paladin prior to cata, and pulled all of LBRS. The mobs had a knockdown. I had pulled enough that they had me permanently on my back. They weren't doing hardly any damage, but I couldn't get up or cast anything. It would have taken them half an hour or more to actually kill me I think, but I didn't want to wait around so I alt-F4'ed and the game said, "screw you" and I logged back in as a ghost Fun times.
