>>Sorcerers get ALL charisma-based skills as class skills. They are a Charisma based class; to deny them the advantages of utilizing their high charisma for anything other than spellcasting is WRONG.
Uhhhh... why?
Yes, they have a high charisma. Why does it necessarily follow, then, that they should be skilled in all charisma skills?
You're tryint to beef up the sorceror from the point of view of just giving him more power. Here's an idea: How about we give him the skills that make sense, in the game world?
A sorceror is a variant wizards. I'm quite at a loss to understand why a variant wizard should necessarily be as skilled as a bard in the various charsima-based skills.
I never use the world Power Gaming, because I think it's 1) snobby 2) juvenile and 3) hypocritical. Look, almost all players are "power gamers" in the sense that HELL YEAH, they'd like more power. (Please don't bring up the various people who swear that their character wields a wet dandelion rather than a genuine weapon because "that's what my <i>character</i> would do..").
But your complaint comes from the mentality of pure Power Gaming. You're not thinking of flavor or game-world-logic. You're just thinking, Gee, what would make the sorceror tougher, and sure, having access to all cha-based skills would do the trick.
But precisely what the hell do all the charisma-based skills have to do with a wild-talent wizard? What is it about the character that leads you to conclude that, like the bard, he would spend the bulk of his time actually developing and improving his charisma-skills?
