Dismantle (http://wotlk.wowhead.com/?spell=51722)
Works pretty well in PvP. I got to drop it on a hunter outside of Scarlet Monastery the other night and he literally just ran. I think it can be resisted fairly regularly though...
Mouse and I sprinted out of the Graveyard last night as the server ticked down to shutdown. We finally got a few kills with moments left. We were about to get another who flagged with a few seconds to spare thinking he could get an easy kill off me. I *know* I delivered the killing blow just as the server died, and I am pretty sure Mouse got the druid. Again. ;D
Dammit! I miss all the fun
Hmm using it on huntards is a neat idea. They're pretty useless with just their pets in PvP.
