I'd like to hear an example of a mechanic that you think would be intuitive and challenging, then. The only example you've given so far has been Bismarck, which is an incredibly easy encounter as a whole and is entirely choreographed with a few slightly randomized mechanics. Nothing about it is new or intuitive or challenging, it simply requires people to perform acceptable dps and not stand in circles on the ground.

What exactly makes that fight a good model? It's everything you seem to be against. Can you give me an idea of what you're looking for?

And perhaps without the shitty sarcastic tone while we're trying to have a discussion?
