Can I post serious suggestions here? Even if this thread started as a joke I'd like to pitch in with a suggestions or improvements of my own:
As you can see from above doctrine list, certain pagan exclusive doctrines seem to be more powerful than others:
zunists can marry up to four sisters (or something like that),
tengri ignore defencive attrition, deal more damage and can have multiple wives,
bön has meritoccratic full gender equality,
africans can remove unworthy ones from inheritance, get more money out of infidels and elders pitch in inheritance process,
norse get kingdom level invasions, river navigation and reduced ship costs,
and slavics can navigate rivers, have stable inheritance (no short reign penalty), and rulers can improve vassal behaviour though piety.
When comparing those two offensive and four defensive to Baltic (eldership succession and resistance against foreing missionaries ) and Finno-Ugric religions (stable inheritance and missionary resistance) the two aforementioned religions seem to be bit lacking, but that's my opinion. You might be perfectly happy with the perks, and maybe religious resistance is that powerful, but if you would be in charge of content design, would you add anything, replace, or remove a perk from these two?
Here's my suggestions:
Romuvan exclusive reformation dotrine would add land morale for defending homeland against foreign religions, in addition for eldership succession and missionary resistance
Suomenusko religious head (if any) can venerate ancestor.
These are just my suggestions, would they be too overpowered, too specific, or not unique enough? Feel free to give your own suggestions how'd you change the exclusive doctrines.
And to get this thread back on topic:
If you have any critique, feel free to post it.
