It's annoying to be promised one thing and to get another, but it's not clear to me from your post whether ANYBODY dove the back wall that day. It's a dive that's highly dependent on wind and water conditions, and the operators often won't do it.
Personally, I found it to be one of less interesting dives I've done on Maui. But then, diving a wall is not a novelty for me. There is far more life inside the crater or along the "arms", for my money.
It's also unclear to me what the problem was with the dive you did . . . Molokini Crater has topography that offers something to people at all levels. Yes, folks snorkel there, but I've dived inside the crater and gone down and seen sharks and garden eels, and endemic nudibranchs, and octopuses. I don't think I'd be horribly disappointed, if the boat told me we had to stay inside the crater and dive.
