All HBD worlds have to deal with the churn of owner. I recently dropped the one world I was in where I did not commish because of time constraints. After 40+ seasons of running worlds, I've found that it EASILY is the most beneficial to the world for a replacement owner to be found immediately once someone decides they are moving on. Inevitably the team is not taken as well care of and/or long term decisions are made by the outgoing owner which the incoming owner has to deal with.
The veteran owners whom I like to attract to these worlds almost uniformly prefer to take over the current budget instead of starting from the standard neutral budget.
Moving forward, if you choose to not come back next season, then you are open to transferring your team early. Preferably I would like that to happen immediately once the roll call is taken, however I understand each of us pays for a full season and if you demand to stick it out through the 162 game regular season then perfectly understandable. Furthermore, NO LONG TERM decisions are to be made by the outgoing owner without prior approval from the commissioner. This primarily is targeted at re-signing outgoing free agents, but trades will not be allowed either.
Very very rarely does an owner from a playoff squad leave one of my worlds. However, in those cases the incoming owner will send a gift certificate to make up for the credits you will be missing out on by transferring your team.
To sum up...the positives are huge for when a new owner comes in before rollover. They get to take their time and analyze their team, they get to promote/demote minor leagues, they get to make free agent decisions, and they get to inherit the current budget. This also helps the other owners in the world as it is MUCH easier to recruit a new owner when they have this option and we don't have to wait for someone to enter the world after rollover.
Sorry for the essay, but I wanted everyone to see I have thought long and hard about this. This rule will make the worlds better and make my job easier.
