Dunno wtf happened to my other post on this but here is the short version.....
Anyone experienced being double death gripped by the same DK? In arena I fought an unholy DK and when even i swapped to his healer the Dk would run away, DG me and continue to run and then DG me again about a half second later which pulled me another 5-10 yards away from his healer. This was particularly annoying because he could effectively wrap me around a corner by doing this. The first grip was would get me to the corner, the 2nd grip would pull me around the corner and completely LOS of his healer.
Don't know if this is a bug or exploit, or if blizzard actually thought this was a good idea and made it legit (which honestly wouldn't shock me in the least, given the moronic things they've done already in this game).
