I think you are mistaking brocoding for RPing, this is an RPg
You are saying you roleplay a guy that sees a friend in the enemies army and runs to him to hugg and greet him?
This is clearly reallistic medival behavior you are roleplaying there.
what about you try to avoid him in battle.
don't go there and have a chat. this would have got both of you killed if there was some military structure.
