From the official site: Accounts are linked to each other. If multiple accounts each have their own character, you can select a primary character. After that, logging in with any linked account lets you use your primary character. Other characters will not disappear, and you can switch your primary character. Regarding ranked: your battle data, rank, and leaderboard on PC, PlayStation, and Xbox are saved separately under your Career for each device. Even though you have just one character, your rank and leaderboard are independent on each platform.
