Charisma is essentially worthless in 2nd edition unless you just want to be respected. There're no sorcerers or other Charisma-using casting classes, and bards are Fighter-Thief-Druids (the 1st/2nd ed Bard in 3.0 is the Fochluchan Lyrist).
Something else I'm not a fan of in the later editions - that every stat has to be "useful" - ie pertaining to a direct plus to a dice roll for some skill gain. Just how does a sorcerer bend arcane magic to their will using their good looks and personality skills?
I know some people say about D&D that you have three physical stats, two mental stats, and one social stat, and you use them in that order ("fight us or give us a quest" style) but I've never found my D&D games going down that road. Adventurers should not be islands of muscle and spell power. Who would want to live that life of powered isolation?
(PS I know this isn't necessarily your attitude, Moondog, just made me think of it.)
It's cool. Particularly because that
is my attitude. If you are going to make me do the extra bookkeeping to keep track of, memorize, and otherwise know what something is used for, make it useful or remove it from the system.
This doesn't mean that purely flavor related things are bad or should be filed off, or that mechanics should always come first, only that if it doesn't matter, make it optional.
I'm reminded of the Comeliness stat that appeared in optional 2nd edition supplements (and the hilariously terrible Book of Erotic Fantasy in 3rd). It did something that was actually 'useful' roleplaying wise, in that it said 'You are X amount of attractive. People react Y way because of this', which differentiated itself from Charisma in an important way, in that Charisma is force of personality and general 'intensity' of character.
It was almost universally panned however, because it actually did very little, mechanically, and only added to book-keeping and furthermore, skewed things in terms of point buy. Most people considered it 'yet another dump stat'.
Charisma as a dump-stat has always been one of my hot-button topics in Dungeons and Dragons. I look at characters in Fantasy literature, see how they inspire, lead, and generally be awesome and highly charismatic. . . and then at three quarters of the Fighter population, all of whom are apparently as charismatic as the average farmer, which is at odds with the archetype.
I think I've gotten off topic, though.
