That's a downgrade in my bookLike I pointed out earlier, they're not allowed to because the unique one is just objectively better.
but it still isn't a bad idea so the player doesn't accidentally or intentionally gimp their religion when choosing given options.
Just some other observations for unique doctrines that would outright replace others since there is no reason one would take the non-unique one over the unique one:
- Totem-Guardians: Religious Tax
So, it's not that the uniques are objectively better in each case. They can very much be throwaways, depending on what you're building.
