Repels and the pike square

I think the length of the weapon should play a role when calculating repel effectivness. Now the game (according to the manual) just checks if defenders weapon is longer than the attacker, and if true the repel check is initiated.
It would be nice if the difference in length could be added as a bonus to the defender, not just as a security to be able to repel at all.

This sounds like a really good idea. The length difference times two or three as a penalty to the moral check would maybe work well. then the attack could stay low, so pikemen wouldn't repel infantry too often (infantry has mostly better defense than cav) so increased so the really big moral penalty from a pike vs. a sword wouldn't imbalance them, but even a 2 or 3 penalty against knights would really improve the repel effectiveness.
This isn't moddable though i suppose, while changing att/def is.
