Brettonia is desperately, desperately in need of the option to dismount their knights in battle as was possible in nearly all previous TW titles.
Sieges nearly always end in a waiting game and an auto resolve for me as Brettonia because 1/2 to 2/3 of my army doesn't know how to dismount their horse. That's insane. The Brettonian infantry are very poor and will break consistently when trying to take walls... which means you have to take a great deal of them -- far more than is reasonable; and this brings drastic income penalties.
Also... as an aside... why are Squires a peasant unit? A squire is a knight-in-training; pretty much always a noble or aristocrat. They are NOT peasants. If foot squires didn't count as peasants that might alieviate the need to dismount the knights somewhat.
But yeah... dismount would be very welcome.
