RTW's move rate are unrealistic but most people would get bored to death. I have to agree that a speed compromise is needed for TW games for normal people or it just takes too long.

Routing heavy infantry is an interesting case though. As much as I'd love to see droppable equipment, it is a gameplay compromise so rallied troops can still fight. A droppable equipment system would be an interesting feature. Shields getting bashed, swords getting lost, soldiers without weapons trying to find one or going Rocky IV on their target.

Charging cavalry as was pointed out in a few places have a few problems that are engine related. Two things: They almost never lose their charge bonus AND armor adds to impact damage.
