Re: OOC2
The classes with 2 skill points per level, have other abilities instead. Often feats or casting abilities.
A fighter with 2 skill points has a shed loads of feats to make up for it :) OK - they are fixed by class, but that is the exchange/sacrifice. The same is true for most other character classes.
Ironically, the class with probably the most in terms of feats, skills and abilities is the bard - and is generally considered to be one of the least powerful classes, least able to take a leading role :) Actually, something I have never really agreed with :) the class just needs playing properly.
I spent about two years doing analysis of equivalence between Classes, as I investigated the possibility of a classless system. I decided that while I could get a system that worked, it lost the 'feel' that went with D&D style games.
Just as important is the average skill level of the world - across all of the characters that live in the game world. Knowledge(History) 6 makes you a good amateur Historian. That really isn't hard to achieve. One trait, a decent ability score and one point spent. It is generally only PCs who have skill modifiers much higher than that.
How many hobbies, extra social skills should a 'rounded' character have? Personally (in RL) I think I probably have three or four non-work related skills that are above 1 or 2. But that is because I have concentrated on developing Professional or (in D&D/PF terms) class skills.
