I agree with you.
I've been progressing through the game pretty slowly so when I hear about things getting nerfed I get a bit disappointed because I never got to experience the original difficulty. I don't know if I would have been able to do it, probably not, but I at least wanted to TRY it.

Supposedly they are going to be nerfing older content when newer content comes out as well, which means I need to go a bit quicker than I have been.
