I still think that game should include warnings ...
At least for dialogue options.
After all, our Paladin (i mean character) know their oaths ... and so they should be aware that saying, or doing certain stuff would break it.
I think this might be a Damned if you do and damned if you don't situation. Those who make the Oath of Ancients primarily lose faith by indiscriminate killing and less so in conversation, which really means conversation ques would almost completely protect devotion paladins and offer no protection at all for Ancients paladins. I feel confident the paladin Druids would call foul at that point and ask for overhead tags on NPC's to warn an archer before they released an arrow that it would break the oath.
Then Larian would spend the rest of their lives doing nothing but making Paladins happy.
They probably have better things to do.
Paladins are big boys, girls, and non-binaries; they can protect their own oaths..... or hit F5 a lot.
