Well, Dom doesn't model neither charges nor formation in a very detailed/realistic way...
The current "charge" is not that bad : Lance is used only on 1st melee turn. However it can't be "countered" by pike formations.
Maybe Pikes could be improved to say Dam 18 w/o Str adjust, AND be usable for say 3 turns, then the pikemen will have to draw their sword ? Historically it wasn't completely like that, what mattered was that the phalanx has to remain orderly, but it could be a compromise ...
And I confirm that even when faced with few enemies (say 50 in 3-4 Groups), in 2.06, cavalry ordered to attack rear usually attack the flank of the enemy FRONT units, and does'nt get to the rear... IIRC it DID it correctly in 2.02
