It's noted in one of those many threads that Kaiten wasn't working with additions they had planned, so it was really less about dumbing things down and more about making sure things functioned as intended. There's no denying the flow is different, but you'll be getting the same result, if not something better. If people need to be sad about it, go cry in a corner or something. Don't start harassing others who are genuinely enjoying it (with a fresh perspective no less).
The hard truth is none of your past experiences matter to those of us who haven't been there. You've no right to attack or try to deny people their joy or difference of opinion.
