What is your preferred 2H martial weapon? A 1D12 like a Greataxe, or a 2D6 like a Greatsword or Maul?
Damage roll-wise, with a Greataxe, you have equal chance of rolling any number from 1 to 12. So the damage can swing wildly.
But with 2D6, the probability is more like a bell curve, with 7 being the highest chance at 1/6 chance and the extremes of 2 or 12 at 1/36 chance each, giving the damage more likely to be around the middle - you have a 2/3 chance of getting a 5,6,7,8 or 9 in the roll.
Which do you prefer? The erratic damage from a 1D12, or a more consistent middle of the road damage from a 2D6, assuming the Sword of Justice is not in the game?
