Chaotic is midcore, in case you were wondering

This is the only thing I can think of, yeah, that they're unwilling to annoy some subset of players who tie some aspect of their self-worth to their video game accomplishments.

You're projecting hard here. I hate the Chaotic fight's design (merely look at my post history and you will see proof of this) but I think that nerfing/changing it would be a terrible idea.
It is not fair to irreversibly change a piece of content that a group of people enjoys, to satisfy another group of people. All this does is reduce the enjoyment of that group for the chance of making another group happy.

It has nothing to do with some sort of "self worth" argument.
