This is essentially removes the only playable builds from the game. Bad idea. How about buffing underperforming builds instead?
I'm shred, and it makes no sense to kill lilith with one hit/duriel etc., also with my pulverize with overpower, I think it's good to make a balance in which all classes have the same opportunities
Finally, ball lightning got incredibly boring very fast.
The vampire powers provided a massive amount of attack speed and it's literally the only reason ball lightning was good, it wasn't buffed between season 1 and 2, in season 1 it was considered pretty bad. Without the vampire powers, they'll probably just kill the skill.
Stop he's already dead
