Shouldn't you be able to clear any content, regardless of difficult, with any combination? If any content requires you to have a balanced setup you can't really tell that Holy Trinity is gone, but rather that it was expanded. I've seen a couple of posts/threads saying that there is no Holy Trinity but there are still roles to fill. Seems just a variation of the same thing. Nor that I think this is bad, I like the idea. Just that the whole "lol Holy Trinity is finally gone lol" is a bit too extreme.
