Use the "chapter: season" language on Odyssey, to differentiate big changes, to create better hype.
For instance, we're still in chapter 0 of Odyssey, and if we were to have started using this at launch, then perhaps mechanical mayhem was c0 season 1, Star wars c0s2, lost isles c0s3.
But we didn't use it from launch, so everything until using it should be c0s0.
This language tool could help diversify changes, as they all won't need to have a fancy title like mechanical mayhem. It'll help to time releasing new stuff, both from an r&d perspective (super big things at chapter increments, more time to work out bugs before release, while medium things can be added at season changes, and small things monthly) and for an audience/player perspective (instead of relying on YouTubers who create hype on guesswork, players will know of monthly, season, and chapter change timeline. )
Particular chapters can have fancy names, devs will know when a new theme needs to be completed by rather than the asap or vagueness as is, hype can be built for the target date within the player community.
Like I don't need to ramble all this, you already use this language tool on battle Royale, you have experience of the benefits.
It'd be super simple to implement too. Have a bunch of new stuff compiled, leak and then subsequently announce "odyssey c1s1 is coming!" and then deploy it, and go from there. It's mostly just a word based mind game, like most marketing, but the effects cannot be denied.
Like is Odyssey out of beta yet? It's come a long way from the super beta nonsense like the 'wood only stacking 30' it started with.
Announcing c1s1 of Odyssey would make it official, de jure, that it's out of beta, no matter the arguable de facto.
