To those thinking you'll be able to "life grip" people off a cliff, i'd imagine it'll work the same as a DK's death grip. AKA you can't use it while you're mid-air :P
And while yes, it's people's own jobs to get out of the fire etc, it's still nice of you if you pull them out of it and save their ass. Everyone makes mistakes sometimes. Not to mention disconnects. It would've been a raid-saver if we had this last week, when someone disconnected just as he got a defile on LK. Defile lands, person DC's, you life grip him, raid's saved :P
