This isn't so much about the mechanics but how the characters of the NPC which have been broadly established over the years are not reflected by their stats. It's more about RP'ing and how as players we react to how they have been written.
So for instance, Alora, charisma 10. 10? That's the same as Edwin's and Xzar's. To me that makes no sense, it should be far higher. Even if you find her tiresome after a while she is undoubtedly charasmatic. It's how she gets away with being so OTT with the cheerfulness.
Faldon, wisdom 16. Now to me wisdom is based on gathered knowledge, weighing up the consequences, being able to see the "bigger" picture. Do Faldorn's actions portray somebody with a highish wisdom score?
Imoen, intelligence 17. It's downright stupid to not use your ability to learn and instead mess around thieving when you grow up in the equivalent of a university. And her strength score is far too low for somebody who has turned to the physical rather than the mental.
Jaheira and Khalid charisma 15 and 9 respectively. Those should be swapped or at least adjusted. I think sometimes people aren't so keen on Khalid, but I rarely read that people actively dislike him. Whereas Jaheira divides opinion, isn't that where charisma comes in? You have broad appeal.
Shar Teel constitution 9. How does that make any sense? She throws herself into fights and surely should have a robust constitution.
Edwin dexterity 10, constitution 16. So a person who is bookish and uses their hands for their craft has bad dexterity and the constitution of a field worker?
Xan charisma 16 Kivan charisma 8. Hmmm.......
So are there any stats you would like to see changed to a more realistic reflection of how you see the NPC?
