I agree with role specifications. Perhaps each having only one role is too limited, but I did a research about class roles in RPG games first. The result was a nice, detailed list – which I still change every now and then. I think this will help me when creating my game.
But, I would like to say, the Thief/Rogue shouldn’t be just a dirty-fighting variant Fighter. Its core is out-of-combat effectiveness. Actually all “Experts” are like this. I think it’s fine for some classes to be somewhat more limited in combat but with greater skills.
It just never really WORKED. This was a BIG problem in AD&D, where the thief was basically pathetic in combat. Maybe now and then he'd manage some critically useful backstab, but in 99% of the fights he was just dead weight that would have been better as a fighter. The fighter OTOH was pretty good at dealing out some good steady damage, but he couldn't do bugg-all outside of a fight. The magic user was meanwhile rolling in options all over the place.
No matter what situation you were in, half the party was basically dead weight, or at best a poor imitation of a fighter just hoping not to get skewered. IT DID NOT WORK.
Rather in 4e you have a party of equals in combat, and then outside of combat you've got the Rogue with his deftness, stealth, and etc. The fighter had his physical prowess, and various other things, intimidation, survival, whatever. The wizard has knowledge skills and (at the least) some free/cheap rituals. So they can each play a different role in combat, and a different role elsewhere, though OO combat niches are generally far less set in 4e.
