With the Boostio/Zikz lineup of 100T the only three maps they have won, is when Asuna has the highest impact on the server. He is perfectly capable of being the best player in the server ESPECIALLY when he is on raze. When he is on they win. When he is not on, they place close but lose.

No, he is not the problem. He is the win condition. All 100T needs is for Asuna to reach his full potential more consistently.
