I'm fine with the Leadership stat's effects, but recently I was thinking about the Charisma stat in general - you need to have 3x Charisma than you have Leadership (and others), but there's no secondary benefits to spending a point on charisma - in effect, there's 2 wasted points of it before you get to the 3rd effectual one. This can get annoying when it's of more pressing benefit to get more damage, or faster attacks, or yet another attribute point. Maybe each point to Charisma could decrease merchants' prices by 0.05% or something?
