There's no Clan Battles and Tournaments Bug
It would be great if you can add: Clan Battles Player Ranked Tournament Free for all Tournament Clan Tournament To resolve the issue of matching system for time-zones, you can set schedules to them similar to how "World Boss" works. "Clan Battles" is basically clan vs clan to test out which clan is the best and bring out rivalries. Much better if wins and losses to which clan are recorded. "Player Ranked Tournament" is 1v1 & 2v2 mode for player with same rank. "Free for all Tournament" is for all rank. "Clan Tournament" all clans can participate to become champion of the season. The rewards can totally depend on you and "business practice" to make this game modes engaging.
