Black Sea Provinces

[V.T. Marvin]

I'm wondering if increasing the devastation effect could help with this. You might have formal control over an area because you've taken the settlement, but there still are vast swathes of land with enemy armies on them, ruining your trade and causing unrest! The larger the province, the greater the chance of this happening and making a difference.

This is an excllent idea! I am not sure whether the devastation effect is moddable (probably not), but if it is, it should be implemented!

It would also make sense for the enemy armies to generate income just by hanging around your province. Not sure if this can be modded in, though.

There is such a thing already in EB - certain factions (especially nomads) gain some money via script if "GeneralDevastatesTile" (or something like that) trigger occurs. You can search for this in the EBBS script (and if you wish even customize it yourself rather easily).
