Indirik,
All religions have desire to dominate and convert everyone to their faith, declaring that or not.
I believe people are disinterested for religion because religion is made powerless.
Temple and shrine upkeep feature disabled opportunity for religion to have some net positive earning, making religions dependent on outside fundings, so they are mostly made mere decorations for those who hold all power anyhow.
That only limited possibilities fto create interesting conflicts, as everything is dependant on heavy funding, and funding is in hands of few, who even do not compete each other.
in real middle age, we could for instance say that otoman military had ruthless soldiers, who had never cared so much for funding as west european middle age had.
similar to mongol, huns, etc.
in bm, all power is currently dependent on funding, military cannot do anything without funding, religion cannot, even there is very little way how any kind of diligent work and dedication can compensate lack of funds, which is pity.
currently, diplomats are also given one single feature where priests have monopoly, and that is influencing peasants, so i daresay religion is made futile by design.
even if some religion stories could have been interestingly developed within religions books and roleplays, so few people are interested as there is little or no effect on mundane world.
the only "cool" feature that stayed is RTO, but RTO is rather harsh activities, and gives no opportunity for religions to act behind the scene, with silent, almost invisible influence, which could be the situation, if religions could be able to earn their own funds to at least some extent.
religion for cities balance is also missing. duke can either use religion as his own profane tool, which is mostly not interesting for anyone outside his small circle, otherwise duke can have only troubles with religion, and vast majority of dukes are pagans, which is really unrealistic.
dukes (and all region lords) should be made dependent on religions, to some extent, for instance pagan peasants should make much more troubles than peasants who belong to any religion, so region lords should decide whehther to allow domination of one faith or to take care that several faiths are balanced in their regions rather than simply doing absolutely nothing besides disallowing any preaching.
every single group of mediaval peasants were part of some religions, and it is simply not so ok that pagan peasants are so cooperative and productive in regions.
different competing powers and groups should be given different powers to be forced to cooperate. given all practicable powers to one group (region lords) simply allows them to not care for others, and that stalls the whole game world.
