I just fear to completely lose interest in the game
Same here.
I enjoy a lot of aspects of this game, but thinking of a demotion is always joined with the thought of quitting.
My trainees have been drafted in august of 2019 (!). It's such a commitment to building a team, one I don't intend on repeating if nothing works out, like last time.
Not to be pessimistic, 'cause the slow pace is also a great part of why the satisfaction of success in BB feels better than in other games. I have quit in s28, only to come back in s30. A break once in a while can do wonders to one's motivation.
Best of luck to everyone, IRL and in game!
