The 3 characters (Ikki Tousen DLC) are important to play this competitive against other players. These characters have substance and include in the game. (the DLC is for free)

We're planning a lot to give Estival Versus some love. We want to play it competitive and we're looking forward to see a future for many years as community.

Its not because of the style, its because of their gameplay. We can't learn anything about these 3, but when we get qued against asian players with one of them, what we can do? Win or lose of course but we have to study them.
