According to PHB 198, which describes mounted combat, a rider can either 1) directly control the mount and make it Dash, Disengage, or Dodge, or 2) let it act independently. Question: how will a 400 GP warhorse (PHB 311) act if I let it act independently? In other words, if I'm spending 400 G on it, it better be charging around, trampling stuff down, and smashing everything in sight with its hooves, right? lol... I guess I just want to make sure that the horse will actually be worth the gold and not just run away or stand around pointlessly. I can spend 75 G on a riding horse who will do that.
