cavalry charges against pikes units

[Pocus]

I'm trying to envision what it does mean if a man with a shorter weapon move in direction of an enemy. Aside from charging, I dont see any other hypothese. I mean, he wont stop all suddenly before his enemy, then attempt to break his defence by play of sword.

=> so in essence you are right, a unit with a shorter weapon moving toward an enemy is always charging. The faster he moved, the bigger the damages he risks to get from the enemy weapon. Your rule would be cool too.
