Has anyone done any work at determining catagorically what different skills and perhaps even more importantly, different skill levels (apprentice 1,2,3; adept 1,2,3) do? It would be nice to know how much I should worry about upgrading my skills and which I should concentrate on at which levels, but I've been unable to find anything on it. Any help is appreciated. If no one has, perhaps we should start a discussion and put what we learn in a forum category/area.
