Unfortunately I would say it is not. I was having no problems with revolutions for me or the AI until the most recent changes, now the ai falls into revolution as soon as it gets 4 cities. Some don't appear to be able to get beyond 2 before splitting due to revolts. A lot of mergers also happen but then the revolts come back. I am playing on snail at noble level - I need to get to where I am testing stuff without being wiped out
