It's not an oversight, it's there to accommodate multiplayer. The game is specifically designed to allow players to cooperate *or* work against each other. You're roleplaying as an individual character, not the entire party.
Make civil abilities only shared between linked chars. Problem solved. Many people play this game in SP. Why should they suffer just because MP is here? Why should players in MP suffer if they control 2 chars?
I think persuation and pet pal should be shared too. All that individual civil abilities add is tedious micromanagem
