I am a person who discounts a bunch of courses that I see as a waste of time (underwater buoyancy, boat, computer), so I can understand your point of view, but if that is your opinion on the cost of advanced than what the hell do you think of tech training!
You might think that tech training is super advanced, but, to an open water diver, the skills you "should" be learning in an advanced class are the same jump in magnitude as an experienced divers training into the beginning of tech. Unless you have an experienced dive buddy (I would hope tech certified, but doesn't necessarily have to be) who can adequately show you SMB deployment, line reel navigation, line tie offs, blind line follows, good natural navigation techniques, different pony bottle techniques, mask off drills, fin techniques, and light signals during night dive you should not be discounting the advanced course.
And if you do have a buddy that can show you all these things. Great. Then your advanced card can be filled with other specialties you can't do with other buddies like Rescue, Search/Recovery, and Nitrox. Maybe something like equipment or science of diving would be good.
