WOW GOLD players can't think of a single thing with a cooldown.
It doesn't even give them insta-runic power. All it does it brings the target into their melee range so they can get some attacks off. Death Knights need Death Grip as they lack: ms, cc, escapabililty. Probably Death Grip is one of the few abilities that gives Death Knight's a chance seeing as: their debuffs are mediocre and dispellable, and their strongest attacks are active disease dependant.Having three or four death knights bouncing a single person around is a ton less CC than a single Mage can put out with frost novas, rank 1 frost bolts, or Blizzard. And it takes multiple Death Knights to do it. And every time one Death Knight bounces a target that another Death Knight is meleeing, he pulls it out of melee range of the previous guy.There is one thing you should bear in mind that Death Grip has a 35 second cooldown. WOW GOLD players can't think of a single thing with a cooldown that long that has diminishing returns. It may end up being nerfed in some way, but adding a diminishing returns is unlikely to be the way they pick. Just be happy most of the Death Knights you will face are dumbasses who use it to "pull" rather than saving it for when it would actually be useful.Now it is the time for us to compare what happens when you get death grip chained to what happens when you get death coil chained (assuming no DR on either one).
