With the Livor Mortis skill the summons AI kind of gets in the way of when I want to get it generate threat especially at the beginning of combat. The summon can't be commanded to engage at the start of a fight which in my opinion makes threat generation a bit lackluster. I think a great addition to this would be to make it so the summon charges to the location of your cursor when using the threat generator to allow for better gathering of mobs as the skill has a small area of effect anyways.
