Biggest thing that creates unbalance is Dawnbreaker of smiting, cheap aoe ulti with knockdown, scaling with mighty CP.
Solituon? Make it knockdown only vampires and werewolfes again ( currently i dont feel almost any downside of being a vamp - that 20% more damage db does is midigated by 33% reduction by undeath passive), or leave knockdown as it is and reduce damage by 25%-40%
