This is something I wrestle with when I run any role playing game. If someone makes a character who is a smooth talker but the player isn't, I sure don't want to make it even more difficult for them to play a smooth talker. I learned from a good GM to ask this question, "What are you trying to accomplish?"Does the build have to be respected, though? Why even have a social "build" if the good role-play must be respected? Conversely, must a player's physical ineptitude be considered when he rolls a critical hit in battle?
