I believe the current range for lords is 400miles, this is actually a significant distance. Instead of restricting it to adjacent regions only, the range can be cut down a bit. To give an example from Riverholm to Suville is 272miles and is 4 regions away. Something along the lines of 300miles should be fine.
Also the restricting offers for 3 days sounds nice, but the time could also probably be cut down a bit too to not hamper food movement too much when regions are starving.
