Just reinforcing two things in particular:
--Siege lag is appalling. I can no longer play my Venetian campaign because the Milanese attack with a huge army and the battle drops to 1-2 fps. No amount of graphics tampering has changed the situation.
--Routing units using ladders sometimes get stuck on the wall (a la RTW siege tower units that just sat in the tower, stuck and unkillable).
Other:
--Router chasing cavalry tends to run beside the routers, rather than over them.
--I could be wrong, but I've watched cavalry as I've tried to charge home and I think I noticed something. It seemed that cavalry will use lances if the enemy is a) charging it, b) holding position. If the enemy was moving in a different direction or skirmishing, then the cavalry would switch to swords.
