In OD&D (the LBB's), all characters used the same hit dice, D6. If you were a fighter, you got an extra +1 here and there; if a mage, you got a -1 here and there. I know it's unlikely, but is there any wisdom in going back to something similar? It would make constitution bonuses mean a lot more, and the HP disparity wouldn't be as great for a few levels.

Would 5e benefit by going to a hit-point-less system like Mutants and Masterminds?
