We all know how activity can decline when a faction FO (for whatever reason) can't put a lot of energy into a faction. Real life, other responsibilities, burned out- whatever it is, when an FO steps down there is almost always a lead up of lower activity which often translates into lower activity for a faction as a whole when there isn't as much to do.
Since faction ownership transfer requests get posted to a thread for Chaos staff and completely by chaos staff, it's easy to see when a faction is undergoing a change in leadership.
We all also know that it can take 2-3 months for a new FO to get the ball rolling once they take over. It's not a matter of someone taking over and boom, suddenly the faction is active again. It takes acclimation and a slow build or a new FO ends up in serious burn out, or potentially alienating existing membership, which also isn't good for anyone.
Since it's come up twice very recently, I'd like to propose that factions having a change in owner get a 2-3 month grace period from recall notices. This gives the new FO and potential new staff a chance to make a plan and get their feet under them, without having to scramble with the pending recall notice over their shoulder.
It doesn't hurt anyone to offer this, and allows MFs that may have floundered due to tired/busy/overextended previous leadership a chance to rebound without additional pressure. If after that grace period nothing has changed then it will be obvious that the faction itself is ready to step back based on total activity,rather than because of the inevitable low that comes before a changing of the guard.
