Please, for the love of all that is holy, stop making the steps for mastery require winning 5 games, then 10 games. That doesn’t show mastery of a civ at all; it’s just a slog. I don’t want to win 10 games with Jin Dynasty now that I have done all the other mastery steps; let me just beat the hardest AI like it used to be, or make both an option. Grinding out 10 games after doing 5 games plus each mastery step is not fun. 0% of players have Jin mastery according to Steam, and this is one reason why.
