Greetings!
Hmmm...well, if the whole helpless, lame and incompetent Stormtrooper thing from Star Wars is going to be a main feature, forget it.
That's one rule I will "Rule 0" in a *snap*
In my view, that kind of reasoning is not "innovative"--but rather, it is going *back* to some things that many of us couldn't stand about 1E AD&D--the whole "My 10th level Fighter can ignore that mob of 1st-3rd level watchmen, and mow through them like grass, because none of them can even hit me unless they score a natural 20!"
Storytelling be damned. I want the players to take pause when they encounter a squadron of watchmen, or a warband of orcs. Yes, they may very well mow through them. Usually they will. However, they can't get too cocky, because there is a chance that one or two of them might get lucky with strong crits and damage rolls, and just jackhammer the player.
That's good. That element of danger keeps the heroic players from being invincible, or arrogant.
Semper Fidelis,
