the 2set skill is still find.
but the 4set skill and 6set skill is too low power,
can change 4set skill with full WW,no
the half duration and effect.
6setskill can change to 100%damage to enemy than max life below 80%,no that 35%max life that so late .
in my suggestion
4set skill change 100%~50% increase normal attack damage
6set skill change after 10times damage target will reduce target 1%of max life
