i would agree with chenier on this, war or peace - doesn't matter , if you do secession without any rp reason it is simply something against good playing practice, call it strategic or circumventing game mechanics.
in game, ruler can hardly have good reason to willingly reduce his own realm - if region is hard to control he will put blame on incompetent lord (even if that is not true). the others may not agree with ruler and that is good cause for trouble and grievances
...in some better, parallel reality. in our bm reality those in power will mostly find any way to avoid any in-game grievance, no matter the costs, even if they would initiate ooc discussion about planned secession.
the only planned secession i can imagine to be fairly played is the one related to some claim or diplomatic resolution, it can by no means be related to region work hardships.
this is perfect example how meta-gaming kills this game and how probably little is done to prevent it.
