Its a spec thats supposed to be about taking down single, big targets, right?
Remove that boring minor trait that does x% extra damage at range and replace it with a trait that allows cleave attacks to hit a single target more than once if there are no other targets within range.
DH fixed, you are welcome.
(yes yes, I know that traps and LB skills and other things need tweaking, let me have my mic-drop moment)
edit – Oh yes, and make the LB auto attack cleave too.
