I’d say 8/10 because I think every character is unique and belongs there besides Raidou.
My only substantial complaint is there should be more diversity going forward with race and age. It’s weird to have a roster this big and only have three dark skinned characters. Give me people from Africa, South America, India, Malaysia, etc. What about a First Nation character? The world’s full of lots of people.
Also I know Japanese culture can be weird about age, but what about a woman who’s old, middle aged, or even just in her 30s?
