Yup...and with FP, its your nuke. With ST now building stacks of HS (which last 30 seconds) I find myself having it available a lot more. I love the feel of the KC shadow even more now. It makes it feel as though you can weave melee in between your kick *** force abilities, which is the way I think the Devs originally designed the class.
EDIT: Yeah sorry, didn't catch the "dps" portion of your post. I cannot speak to that, but its a must in a tank build.
