Zac's new ultimate also fails in the character department, Zac is a fun guy that jumps around saying "Wooo!" and is all wobby and jello like. It totally fits his character to have an ultimate where he just jumps around causing a disturbance to the enemy team. You jump in and then speed boost jump some more knocking everyone around, its perfect.
Whats the new one? Oh, you jump in, STOP MOVING, laugh sinisterly and pull people away from their team, what? Wheres the sense of movement and sillyness? Its so terrible, even outside of the poor numbers.
And on a bit of a side note, when are you putting out that new tank item review vid? :p
