Many good news but this:
"Removed Byzantine Cores on Chios, Naxos, Trebizond and Corfu to try and keep it from constantly popping up again after annexation."
If i may. I think it's a wrong and non-historical answer to a larger problem.
Islands usually go away because it's hard to make amphibious warfare and inconvenient to keep army on theirs.
Another thing is the difficulty to face revolt when your country has only one territory: because you can't increase autonomy on the capital, your tiny army is usually wiped out be the revolt and you can't rise a new army from another territory.
Naxos and Corfu combined the two problems, Chiros is the fornlorn island of a "kit form" country, and Trebizond is a single territory state usually sucked in everlasting and endless wars.
But in fact you can easyly extend the issue to Chyprus, Rhodes, Corsica, Gotland, etc...
Rhodes, even with the +2 bonus from Knight tradition, no overextension and no war trouble still have 6,25% of unrest. Even with the rhodian army on the island and +3 stability you still have 2,5% of indomitable unrest.
The country is stuck in an ever warning policy and constant use of harsh punishment.
To my point of view, a better way to deal with this is a two (or three) part solution:
- Every capital province should have an unrest bonus, +2 for example.
It makes political and historical sense, it compensates the impossibility to increase autonomy on capitals and it's a salvation for countries with only one territory.
- Isolated territories should have a specific handle of their autonomy. For example, 2 or 3 times quicker (10/15 years instead of 30 years) and with more impact on the territory (-15/+15 instead of -10/+10).
It also makes political and historical sense as countries usually give large and scalable autonomy to their islands and dominions with no core neighbour to avoid having to maintain order by force.
- (Another point may be to reduce the chances of a random revolt event if a country holds only one territory.)
If you take this two (or three) points together there will be far less "constantly popping up" of "Chios, Naxos, Trebizond and Corfu"... without removing any strategical and historical core !
And in addition you also help resolving the others "constantly popping up" islands, small or sliced countries problems of the game.
For exemple if you focus on Geneva. Ligurie will be safer and all territories might be given strong autonomy during harsh times but potential recovery after, because they are all isolated. That will help Geneva from crushing down due to revolts after loosing a war, wich is ordinary the case.
Of course if Geneva give autonomy twice in a row (10 years and 10 years) the country will lose all is economical presence in some areas, but as a fragmanted multicultural and multireligious empire which most of the incomes came from trade, keeping revolts low is far more important than taxes.
