You clearly don't understand how positivity bugged UH is..
100% Runic Power from one spell while under AMS, which shouldn't. It should do a small amount based on how much AMS damage absorbs, and when 100% of AMS has absorbed THEN you can 100% RP, not from one pathetic magic hit.
Runic Corruption giving 120% haste when it should ONLY give Runic Regen.
Pet being able to hit through LOS, so can run through walls and columns at healers keeping them in combat and dpsing them while LOS'd.
SS damage is fine, have you PvE'd recently, UHDK is one of the strongest DPS atm, believe it or not SS is your main ability in PvE, so PLEASE tell me how the **** it's wrong when its not, cos I've even went to test on AT and the damage is similar (AT more gear, DS Gems etc). Your not speccing into RoR, don't complain if your SS doesn't hit for a lot, cos I tell you mines hurts like a truck.
Desecration overlapping, it should not, nor should it activate when a target is immune to Movement Slowing Effects (Hand of Freedom, Disc Priest PvP 4set, Divine Shield, Master's Call etc).
UHDK on molten is not skill, it's bugged.
