Re: What to do - Telling sensei their waza isn't good any more
So... Is this an unaffiliated dojo where the instructor never visits other dojos to train with peers, or attends seminars? Does she encourage students to attend seminars or does she encourage you to only train there and never deviate from just one right way to do a limited number of things? Are you on your own plateau and frustrated, or as sometimes happens, has your training reached the student equivalent of late adolescence so that you need to separate from your teacher and part of that naturally involves finding fault?
I ask these things because your follow up post does very little to clarify your OP.
