You make a few good points but as for the title of it being Knights of the Old Republic and therefore must play a Jedi is pretty damn weak. Carth Onasi, who I consider as much a knight of the old republic as any Jedi, is most defintely not a force user. Being a Knight is more than having power in the force. It is about the attitude and drive to save something you hold dear no matter the cost. Carth Onasi, with all his faults, is a knight of the Old Republic.
