I suspect we actually agree completely, Ith. But since I play skill based PC's exclusively (that's what is fun for me), I know from experience that in ALFA NWN2 they have very limited opportunity for income and advanement. I'm happy with that, because I play for RP anyway.
It just rubs me wrong when I see skills being parsed as some sort of PGer bluff and the threat (implied or real) that skills will be haked and reduced to prevent PGing.
Skill use doesn't generate wealth or XP in ALFA (although admittedly effort has been made on BG server to alleviate that dispairity), they are useful only for RP and party support.
Income and XP are only available via chopping up monsters, and skills don't help a PC do that. While it can be argued that some rogue skills can help a PC in combat (i.e. Dodge, Evasion, backstab), these only help in party combat. Just try using them solo and see where it gets you

.
My point has been throughout that if there is a percieved need to prevent PGing, crippling skill use will do nothing to alleviate that, and in fact will only increase it IMHO.
It must be a failing of my choice of words that continues to cause people to think I want my PC's to get rich and be uber IG.
I don't: I like RP.
I like partied RP.
If getting wealthy was a priority for me I would roll up a fighter/cleric or something and concentrate on chopping up monsters. Though, in truth, I really have no idea what class/race is best for generating wealth and advancement IG.
What I do know, is that it isn't skill based PC's.
