I SEE NO PROBLEM ON MY CHARGE TOO... when charging consider:
1.you must be a couple of distance to your enemy
2. charge infantry and archers 'cus when you charge a spearmen no matter how long you are they get slaughtered up front.. if you must do it at the rear there asses is softer than those pikes in front
3. if you want a rohirim style, charge with 2 or 3 units in a single enemy line and just push those at the back of your calvalry to front surely they would knife through and when they do turn them around and let them shout... ROHIRIM!!!!! CHARGE... again this time at thier rear if thier still enough of you units

in any case cheers...
