Player commendation system is an ultimate solution to building positive environment in this game. Positive incentive mechanisms would completely revolutionize players behaviour. Player contract doesn't do anything but intimidates and scares players giving them nothing in return. Adopting Final Fantasy 14 commendation system in similar fashion can truly make profound differences in this community.
Try not to start game vs game debate, as there is nothing here to talk about. These are independent systems that can work (and do work) anywhere. Thank you for coming to my Ted talk under one minute.
