Glory to Marik
Maybe this is a Morlock logic puzzle kind of thing like in that movie The Time Machine. "If TSR never invented their mechanics, WOTC never would have changed them!"But isn't most of the TSR Era D&D just name only?
Most of the mechanics, design goals, and fluff has shifted always from those of the TSR days. Score, races, classes, levels, AC , saving throws, etc in 5e all work differently and run on completely different design philosophy from the pre-2000 days.
