Thought only the penalty to the group was being removed in velious? Could easily be wrong on that.

Fun ranger tanking weapon. You don't need to be as worried about swing threat when you're shooting spells between swings. This thing procs a pretty strong slow that can really reduce the damage you take. Very good for duo/trio where you might not have slow but don't want to share exp with another player to get a plate tank or slow casting class.
