I wonder whether warrior monks have different look for different civs, like Sohei for japan or Crusaders for European civs. Also, I really like the unit design, but I wonder how well they will be in actual game. Strength through experience works well for for Scouts, but they also get experience for peaceful scounting and have upgrade in the middle. I'm afraid, the time window for training rookie Warrior Monks will be quite narrow as they'll become cannon fodder soon. You'll have to build them as many as possible early and send to war to get them to full power.
