I am still unhappy with the current stability calculations. Take this for example:
Context: I have had (to use) a Golden Age in 1500, haven't whipped anywhere except the 1 city (last turn) since then, had almost all cities grow substantially since then and....still I am unstable because people don't like me, and since they dont like me I get random events making them like me even less.
My domestic stability still suffers a whopping -4 from unhappiness even though basically all my cities are happy.
And my economy is 0 even though I am using several nice cottages and have my cities grow.
And in return I am classified as unstable.
The situation was pretty much the same in 1500AD only then I had mongolia as my neighbour and I was forced to start a Golden Age so I dont lose half my empire because China gets reborn while I am considered "unstable".
This is not only pretty annoying but seems really counterintuitive and I don't think that this situation is really intended.
TL;DR:
- foreign stability sucks because it's always negative
- economic stability sucks because it's usually 0
- domestic stability sucks when you run (or ran) slavery because that malus carries over far too long.
- being "unstable" because your modifiers are "-1" sucks.
