The heads of the official faction team must act swiftly to make unofficial factions official before the playerbase fully dwindles. Delaying this process risks further stagnation, as players become disillusioned with a lack of fresh roleplay opportunities. New factions bring innovation, excitement, and dynamic storytelling, which are essential for maintaining player engagement. Without these additions, the server risks becoming repetitive and uninspiring, causing both veteran players and newcomers to lose interest. By promoting new factions, the team can reinvigorate the community, attracting new players and keeping the server alive. Timely recognition of these factions is crucial to preserving the server's growth and ensuring it doesn’t fade into irrelevance.
TLDR; Make unofficial factions who deserve it official before the server dies out fully.
