I would just prefer more ways to use the stats I have in dialogue. So if I have low intelligence, It would be hard to comment intelligently or knowledgeably about, say, a conversation about history. Gale and Lazeal might be able to, but it would be a hard role for me because I specked a character that is not well read or particularly knowledgeable. However, I should be able to use wisdom or charisma to glean another aspect from a convo. High charisma, I could catch the tone and attempt to commiserate with the speaker, like Wyl would. High wisdom, and I could comment about the potential lesson one could gain about the fact just heard, or speculate on how the new info relates to grander goals. Same with all the other stats.
Idk…I just wish overall for more ways to use the stats I have to bypass my deficiencies. Provide more ways to hammer the same nail, in convos particularly.
So I like the idea!
