I am tired of not being able to catch small raiding parties with my nords. I believe it is historically accurate that the Huscarls used horses for transportation, and were able to catch William at Hasting thanks to their horses. The horses they used were not suitable for cavalry action, but still were quicker than walking. I'd suggest the higher tier nords have crappy mounts and perhaps an automatic 'dismount' command at the beginning of every battle.
