The most frustrating part for me in RTW is that the AI overrides the user way too much. If your horse archer wants to skirmish this way and you want to skirmish that way, you have to turn off skirmish mode or the skirmish AI will keep on overriding your orders. Same with fire at will. They'll ignore you and keep firing on whomever they want to fire, not who you want them to fire. Sometimes, they'll fire 1-2 more volleys, follow your orders for 1-2 volleys then go back to their initial target. Grrr.....
