Everytime you cast Kill Shot kill shot does X% weapon dmg and if you are BM your pet dmg increases by X% per shot and if you are SV it refreshes your Serpeant Sting and increases the peroidic dmg by X% and if you are MM wild quiver dmg is increased by X% and the proc rate is increased. it would keep the rotations the same but increase the dmg of the hunter during execute phases.
