I would still love to have some type of slow or paralyze debuff at the end of our combos. Maybe it would be cool to have SP be an aoe and combo with overpower.
That way it becomes more of a trash pack / multi mob skill it wouldn't need a threat bonus or anything.

I also think like a lot of others, that the self healing needs to scale better. I don't have any good math for it, but yea I can see where it could need some tweaking. That and let the gld increase healing skill work with our healing. Since that is one of the classes we can draw skills from, the skills should at least work with ours.
