I agree that it lacks diversity, but I would argue that the lack of different skin colours is the least of its issues. Everything starts from the fact that there are only 6 playable character models right now and while they fit a lot of the cast, the homogenization that brings to the table can’t be ignored and it does hurt some characters directly like Ito. Since he is much more buffed in the arts than his standard tall male model allows in-game.
Then we have the gameplay homogenization. Inside a weapon group, the standard attacks are basically the same and while there is some differentiation with the special attacks, they are still only a small fraction of the whole and alone don’t create that much diversification. This brings us to the characters, there is a lot of space to develop these guys into their own entities but the vast majority of them are just background filler with the most basic of characterization.
So yeah GI lacks diversity in terms of skin colour, but it also lacks diversity in basically everything else. The Gacha mode did work great in the beginning, but now it is starting to clash with the size and the open-world nature of the game more and more with every expansion.
