I think you need to play with people you trust instead of assuming the worst of their decisions.
Jeff Carlsen said:The broad version is definitely better. Skills are supposed to be equal. As a DM, I will essentially allow anyone to trade one skill for another if it better matches their character concept, regardless of duplicates. The only place I might limit that is if everyone starts wanting the Perception skill.
I think these are two key concepts in the spirit of the game. I've always been of a mindset that players should build a character concept, then try and match the character sheet to that. Rather than just building an optimal build. Mixing roleplay and roll-play together so that they complement each other and everyone has fun.
