I can understand wanting to grow them if you're flat to fit better into a dresses but you don't need DD+'s for that

Smaller bands look small even higher up the alphabet. http://www.brabandproject.com/gallery/search/band/28/ And for me, at least, it'd be nice to just be able to wear bras in one of the more conventional band sizes.

Many of the threads here make breast enlargement sound almost ritualistic

Of course. You won't get anywhere if you don't make it part of your routine.

You can also do a lot to lift and widen the breast though it won't increase breast mass above the muscle, of course, which is mostly fat and connective tissue.

Well, that's the crux of the problem, isn't it? I want more breast tissue. I'm trying to exercise, too, but I doubt that will bump me up very much.

Add to that the claims made in many threads here, that some NBEs have other beneficial side effects and the effect can be positive

It goes either way. I can't think of a method (besides hypnosis?) that doesn't have the potential to go badly. The chances would be even higher if the person didn't know to keep an eye out for symptoms.
