cavalry charges against pikes units

[Pocus]

I feel that the lack of specific bonus against charging units which mostly use momentum as a mean of attack (initially at least), when you use a longuer weapon, is a feature missing in the tac engine. I dont feel that the 1 hit of a repell attempt model rightly how difficult it would be to charge effectively with horsemen a square of pikemen. In my opinion, if a unit with a shorter weapon move at least xxx squares (xxx to be determined, can be 3) then it should be considered charging, and suffer greatly if attacking a longuer weapon-equipped unit.
