Well unfortunately, the training methodologies DONT stay the same. Not when every dojo is different. Some spar, some dont. Some train with other styles, some dont. Some people have experience in other arts, some dont. IMO, this is the main problem with the Bujinkan, and it needs to be addressed FIRST before anyone talks about solving its other problems. Until there is a standard or set training methodology, there will never be a debate that can be answered truthfully.
