[Wahnsinniger]

I don't recall/understand what the current system is, but pretty cool and well-thought out. Though it does seem that perhaps the percentages could stand to be slightly higher. (A Mammoth vs 3 Phalanxes should probably have more than 3% Chance. Perhaps add defender fatigue in there as well?)

I don't know if it balances well, but I do like the Weapon Length over 10 doubled though. A good analogy would be building a brick wall against a current of water. The first brick or two would impede it, but only by a marginal amount. But once there's enough bricks, each one would cut the area the water could go through by such a percentage that it would really start to add up (i.e. doubled)
