The extra factor is every season your stars get one season older
What you have done by staying in the ABBL for as long as you have, is quite an achievement.
Back in season 20 I made the decision to sell off some good players whilst they still had value.
Perhaps I could have stayed up for 2 or 3 seasons, but if I had of stayed up, all that would have happened is that the good players that I had at the time would have aged and continued to lose value
I couldnt see a path forward that would take the team to the top, that didnt involve taking several steps back.
That said Fishy, Urmumma & Koops have all managed to restock the vault without dropping out of the ABBL and have all won significant trophies whilst using this strategy
