Hi Xyth,
really enjoying this version. But still on the dissent mechanics... I'm always playing on Emperor or Inmortal difficulty, and I don't see my opponents having to struggle against the dissent at all, even if they are extremely large. I'm posting my saved game, that's on small size map. Filipe (Spanish) is holding 19 cities from long time ago (for sure more than 100 turns) while the others we are around 7 or 8, and Filipe have not faced any rebellion or civil war. Actually I didn't see any rebellion since this beta version.
But yes, I have serious problems to face with the dissent. That's something I like to deal with.
In this saved game, I've checked with WorldBuilder the city info for Spanish cities, and they have no dissent. They aways have a very big surplus of Health and Happiness, even if the cities are size 15.
