Recruit

I liked training fields in Warband. It was good interactive feature.
Or do something like some of the mod did in Warband. To train your troop, put your recruit in your castle/town, has to hire someone, and then pay an active cost to have your troop train, and there is a finite amount of troop you can train per day (maybe with some adjustable quota/capacity). So basically, pay a premium for your convenience.
The way it worked in Warband was just bonker broken. Get 100 farmhand together and 2/3 of them become regular infantry in a couple days while you don't have to do anything? No more of that please.
