Wasn't going to add, but there was a point I thought unmade.
One of the secondary benefits of having a stat dealing with Appearance is removing that aspect from the 'charisma-style' stat. Without removing that aspect, the 'charisma-style' stat amalgamates many other social skills with the quite separate outer appearance.
To some extent, all stats are such multiples, but the this separation is better suited to a game with a high social component and less important to a combat-centric game.
For example, I do run a social heavy, skill based game, so I purposely made Charisma and Appearance two of the 7 stats. We have only 4 savings rolls, but one is a 'social reaction roll' made every time a new perosn is met. Appearance is very important for this and similar skills that deal with impressions.
This frees Charisma to be more about actual social skills and magnetism.
But what do you expect from a guy who has a skill tree uner "Basic Carnal"
