None of this has to do with PvP and they explained why they removed it. Simple as that; it created situations where in PvE certain mechanics are nullified in a way that isn’t good for the game when the same ability also regularly causes groups to wipe and is part of someone’s normal rotation. Those three in combination is an amazing recipe for disaster.
Which is why they went ahead and made Death Grip more potent by making it able to move more mobs. Simple as that.
