Players who log out of a match before it ends will be given a penalty that will prevent them from participating in Dragon Ball Fighterz online game modes.
This implies that players will no longer be able to enjoy online games, with or without friends, as well as online events, and they will be forced to play offline (story or arcade mode against an AI) or locally.
However, the sanction can be much more severe if it turns out that the players continue to ragequit. The sanction can then become permanent.
Punishing players using this strategy to avoid losing points in the standings is an excellent thing, thus allowing to bring a better quality of life to the players behaving.
Like the anti-cheats on FPS - which are sometimes lacking - this is a solution to try to make online games on DBFZ less toxic.
