The only DLC character I like is MR. The others are basically copypaste or they feel unnecessary. Also, the fact that they replace Bankotsubo for Nyotengu is unforgivable.
I think what Hayashi offered in that interview was his team's opinion of the situation.
Unfortunately Koei calls the shots and not so much the team. And thus, plans changed. The greatest tragedy our industry has is that developers have no power whatsoever at the end of the day.
