This flaw deals with a player by player preference for chance. We've all seen it, sometimes players prefer the wild variance a roll of a d20 with its epic success and epic failures each occuring 5% of the time. Others prefer the nice predictable bell curve of 3d6, with no "natural 20's" or "natural 1's" ever to come up.
Rather than forcing different these players to play different games in Piecemeal, I make it a choice. A character (or NPC) can always take the "Joe Average" trait. When this trait is chosen a player rolls 3d6 anywhere they would normally roll 1d20. This makes their numbers more bell curve and prevents epic failures and successes. Now on the one hand, the d20 can roll 19's and 20's and score higher....on the other hand it can also roll 1's and 2's and score worse.
Its a very balanced trade-off and nicely caters to all gamer tastes. Which do you prefer?
