I'm with ya, Trep.

As a (lame) example, in the basic Neverwinter Nights, there were a couple of puzzles that were class-specific. For instance, there might be a puzzle that applied only to thieves. In order to have solved the puzzle, your thief needed to have completed some earlier tasks and be of sufficient level to survive the puzzle. Solving this puzzle led to a whole unique encounter and a chance for bonus EP.

Unfortunately, the "puzzle" consisted of an incredibly easy "riddle" that was made glaringly obvious if your thief had done his job of checking out earlier areas for traps.

But.... it was a step in the direction that I think you are talking about... and one I would encourage wholeheartedly.
