So why was big snowball kept?

Playing backline into a champ with a gap closer + big snowball = unplayable.
Playing frontline/assassin into a backline with big snowball = unplayable.
I dont even care about the ridiculous dmg numbers on it. Just reduce the speed or make it ramp up speed like nunu w so its actually dodgeable. It just seems to me there is close to zero counterplay if the person with the augment has the skill of silver or above and their monitor on to aim it. Sorry to complain, but im tired boss.
