While technically Season 1 is ready for live, our initial feedback on the systems have been that it needs some more polish and balancing before it goes out to the rest of the playerbase as a whole. We have some plans to address these issues so Season 1 will go live next Tuesday instead and will run until February 1st of next year and it will be the primary test bed for some potential polarizing features before we determine if they are something we want on the main leagues or should stay in seasons instead.
99% of this update is backend work or features that aren't accessible unless you're on a seasonal character.
