With removal of disengage from jump, nerf to high ground is another needed advantage. While combat has been much much better with patch5, high ground is still the answer to all problems. Concept it self is good, but advantage is just too powerful.
Removal backstab advantage made melee combat more interesting, and same will happen to range combat. I would advocate to try even just extended range, and see if it still makes high ground desirable. Maybe add small bonus after that (+2 to hit).
