- non-accepted culture penalty scaled down from +5RR to +4RR (vanilla has +2RR). It was just a bit too much.
- religious center missionary strength modifier down from -5% to -2%. That's a modifier Rome and Mecca got around 1.4 patch, I hate it, and I'm really tempted to just kill it completely, since it makes Rome close to impossible to convert even with very big stack of positive modifiers. Rome has such a high base tax (which only grows as game goes), and such a small and unlikely to be accepted culture, that it's very difficult to convert anyway, even without this penalty. Mecca has lower base tax, more common culture, but it's Sunni for an extra penalty, so it's also pretty hard to convert. Why either of them needs such extreme penalties to switch makes no sense.
