Inspired by the closed question: DnD Next Hitpoint Inflation,
There have been claims of HP inflation in dnd-next, and there certainly were increased in the absolute value of HP in 4e. In order to objectively assess these claims, we must look at the mechanical-theoretical model of damage across all editions of D&D.
Therefore, at level 1, all things being equal, how many rounds does it take a goblin to drop a Fighter, a thief, and a Magic-User?
In order to ask this question: we must assume conservative builds on all sides, the average hitpoints of each of these classes, and the average damage (including to-hit adjustment) of the goblin in every edition.
If there is significant deviation in 4e, this might provide me with the necessary data to house-rule 4e into a "gritter" experience for purposes of a Break & Enter game.
