Not wanting to muddy the waters in any of the other engrossing threads on martial/caster disparity. OR the rogue threads I was wondering about Ad&D mechanisms for balance in the form of separate XP tracks.
Obviously there was more than that (fighters got strongholds and kingdoms for instance) but rogues progressed much more rapidly than wizards (2 for 1 almost?) and so on.
I'm just curious if that metric has been thought of by the community to any serious degree. It seems to me the rest of the system could be left mostly intact (minus some feat tree trimming just on general principal) but could XP by class provide a relatively simple means of re-establishing class equity (rather than balance because obviously if some progress faster than others the system is acknowledging imbalance).
Anyone have thoughts on this?
