Hallo!
I think that it is better to decide team name and machine color design as indispensable items.
Because it seems to be beautiful and clearer when all the team's machines are colored when you see the "Ranking" page.
In the league where I participate, many people have not completed the color design of the machine and some even have not decided on the name of the team.
In my opinion, since this game is a game that manages the race team, I think that it is better to have more attachment to own team.
