I'm not going to bother reading the entire thread, but here's my two cents.
It's fine the way it is now. Sure, it's annoying that they're constantly dumbing things down, but with easy heroics it gives everyone something simple and easy to do when they're bored.
BC heroics were a pain. The rewards were useless to raiders, and too much work to want to do just for fun. Plus getting stuck with retards was that much worse. Nobody right now can say they enjoy getting HOR as a random, I've spent a ridiculous amount of time wiping in there because of how stupid the majority of players are. And HOR is still easier than most BC heroics.
Everyone's just hung up on a mix of nostalgia and hipster-ness (I PLAYED THIS GAME BEFORE IT WAS [insert something changed here].)
