The Sak breaks it down.
There are 3 fighters [Lucina, Dark Pit, and Doctor Mario] that are alternate models (clones) in the game. Each was originally a color variation, but during development, they were given balanced characteristics. Since their functionality had differences, forms were separated from each other. However, it was vital that this didn’t increase the required man-hours. Some relative tuning was sufficient as it wasn’t necessary to create balancing from scratch.
This is like a free dessert after a luxurious meal that was prepared free of charge. In a restaurant with this type of service, I don’t think there’s anybody who would say, “Change this to a meat dish!!”
Yet, I’m told [to do that] about Smash Bros. But, I guess since a lot of them are children, it cannot be helped.
