For everyone who was waiting for a paladin class to appear, there is a mod at last on Nexus: https://www.nexusmods.com/baldursgate3/mods/122?tab=description

Datamining has shown an unsatisfactory level of writing for specific paladin dialog as it is now (not much thought given, generic, too shallow for me), but still, I would be happy to try this one after most of the current bugs would be fixed.
