I like most of what I hear in this diary, but the system seems to carry the same inherent flaw as EU3: oversimplification.
Keeping things as simple as possible is usually good for a game, but making conversions all-or-nothing affairs damages gameplay in my view. We don't need the exact percentage of each religion in a province (not that I would mind), but having no minorities is weird. Something like "small", "moderate" or "large" minorities with minor effects on the province and the possibility of an uprising even after the first successful conversion would be nice.
