I think the death rate is good, if anything i was a little disappointed at the start of my new campaign because I didn't feel like enough characters were dying when I scanned through the map :/ But then the black plague hit and it was great. I'm using the default epidemic setting
My first game with TRD was as the King of Sweden in the last bookmark. The family is small (only 4 members, 1 male, matrilineal off) and he died in battle shortly after. It was game over within 30 years but I love that!
And not including the black plague, the death rates for characters seem better than they were before. So one question to confirm: with The Reapers Due, are illnesses more common and deadly now? I wasn't 100% sure of that before. I appreciate it because I'd rather not see christian dynasties extend to have 40+ members and grow even further.
Remember, the new custom settings are pretty helpful because you can reduce how frequent outbreaks are
