Game seasons are not really the same thing as live service games though.

I’m really not into Tekken but there are games I play that have setup. Of course probably the most famous of all been Foxhole.

Anyway the point is that without “seasons” (simply called that because it harkens back to TV not because there are necessarily four in a year) there isn’t really any natural conclusion to the game, so you have short tournaments and people rank up within those tournaments, but obviously you don’t want the tournaments to go on for too long because otherwise there’s no way in for new players as they’ll start way down the rankings and not be able to compete. The solution for this is to reset everything every season, but then you’ve got the problem that people learn the meta and are able to rank up to high ranks almost immediately, whereas newer players don’t stand a chance so you haven’t really fixed the problem, the solution to that is to change the meta every season. That way everyone has an equal chance of working it out for themselves and ranking up.

I’m pretty sure they even did this with OverWatch back in the day.
