My thoughts exactly. Say we got 10 nobles and 5 regions. In the old regions, we possible could not hold onto any more regions, as it would cause them to revolt due to lack of estates, meaning many realms had very little reason to go to war (other than because TMP ordered them to). If with the new system we'd gain more gold with 10 nobles in 5 regions than with 10 nobles in 10 regions (because realm size penalties, lack of knight tax tolerance penalties, and 50% tax loss penalties for wildlands), then we really aren't improving anything at all.
Don't be absurd.
There's an enormous difference between "if we expand, we will lose the regions we already have, and won't be able to support the new ones" and "if we expand, we won't make quite as much gold from the regions we already have, but we'll add another region that also doesn't produce its full potential".
BattleMaster is never going back to the days when you could have a half-dozen people running a 15-region realm, and I can't see any rational argument for why it should.
