I have a 70 prot warrior in Heroic tank gear--undead for the funs of it. I will try this and its also common WoW myth that the best way to take down a multi boxer is to kill the brain. This gives us breathing room especially as theyre killing your tank. I played a hunter for a good while in the 70 BGs and you would be amazed at how many people even on 1v1 would try to kill my pet before hammering on me letting me have shot after shot for free on them. The fact that the OPs tank is getting smashed upon and not his shammys to me is no surprise at all.

Oh btw on CC a hunter can also fear other peoples pets ;-)

Warriors hamstring also has potential in this set up V melee types attacking your shammys.
