You take five regions, put a Lord on each one, and have no problem keeping all 15 of your regions under control. Sure, you don't get full gold out of all of them, but you're still taking in some more gold than you were before you took them, plus the extra food.
Does this mean that a realm would always have an incentive to take additional regions, with diminishing returns, or does there reach a point where taking additional regions would actually harm your realm, as it does in some cases under the current system? If so, at what nobles:region ratio does taking additional regions start doing damage, overall?
