Out of curiosity how do you exploit it in your favor?
Where should I start?
Don't want to show everything, but the most common way to use it is to wage war against the Ottoman empire and fight teeth and claws to get one of their provinces separated from the rest.
Next you give them mil acc and ignore them. If they ever declare on you they go in with -3 stab and you get a nice "revolts in Ottoman Empire" modifier towards your peacedeal soon.
Ottos refuse to convert anything early on and eat a lot of minors. Rebels will eat them alive, making any start close to them a lot easier.
Still trying to have rebels force convert them to Christian just for fun, but I haven't found the time to actively pursue it so far.
Another minor thing is they do not understand is that diplomatic ideas lower the impact on stability from decisions.
You can RM your biggest threat's ally and despite them having filled out diplomatic ideas they will never join a war against you.
Pretty hilarious considering another exploit is to continuously RM them and have them break the RM.
Free stab hits every ~10 years in exchange for one diplomat being occupied for ~3 years sounds like a good deal to me.
There's a ton of stuff in there. Not sure how much of it got fixed, but I just checked and can confirm at least the mil acc exploit is still alive and well.
I recommend figuring out most of them yourselves. You start focusing on your game a lot more and end up not needing any of them to succeed.
Great for RP games though if you don't want to do anything but fool around anyways.
