I would say Yun Seong too, but with the return of Hwang in the game he becomes 'obsolete' like "another Korean male character using Dao".
You say this when we've got Mitsu and Yoshi, Kilik and Mina, Raph and Amy, Sophie and Cassie. You of all people should know by now it's nonsense to think that certain legacy characters are redundant because of weapon class sharing. Remember when people said they don't want Hwang back because he's boring. Funny how they all shut up when we got to see how he played. What I find funny is that even though Hwang turned out to be cool as fuck, those people ended up targeting other legacy characters saying "Rock is boring" or "Li Long is just another Maxi". Just don't listen to these shit opinions, Project Soul have proven themselves time and time again they are an incredibly creative team. You know as well as me that SC6 is the best game in the series even with it's infuriating online jank. Have faith ye thirsty Yun fan.
