Gotta admit it...Yi needs his old passive back SPECIFICALLY because of sated
Think about it. He swings too many times in a short period of time compared to anyone else. It isn't even funny. He needs the old 7 swing counter with the full damage extra swing. Atleast sated will not make it do a billion hits.
2 swings counts as 3, so the next swing is a double, which procs sated, making it a third, and on the next sated, his passive procs again.
That means in the course of 6 swings from any other champ, he gets 3 additional swings from his passive. That is nuts. In fact, kogmaw can barely pull that off full build.
He can pull that off the second he gets sated.
