This is a server made by fans, not a official discord server by runix.
Basically its a server unofficial of the community of the game, here you can talk with your clan members easily and talk to other people, here its more easily to match where the server your going to play and which friends are going to play. You can declare war to other clans if you want.
Here you also can report hackers (with a screenshot or video), then we will send to runix games.
In conclusion this is a server maded by fans for the community of the game (justice rivals 3) and which has clans system.
