You are attacking Blizzard for the wrong reasons. While they are horrible with some of their pricing schemes and money grabs that sometimes are purely unethical in terms of e-sporting (see milking transfers from dead servers and indirectly selling gold with pets etc.), they are definitely not without offering a challenge
I lived first hard the Heroic Ragnaros era pre-nerf. Sure, they nerfed it after a while and sure there was normal mode, but if you wanted to prove you're a "man" you had plenty of space to do it while it was unnerfed and insanely hard (especially in 25).
So yeah, you can badmouth "carebears" all you want but you have no excuse: Tons of people had an opportunity to kill such a boss while at its hardest and very few achieved it. Be a Hero then.
edit: But, I will realize that as many MMOs out there they are milking grinding so much - mindless grinding that needs almost no effort, just to milk monthly fees - that I do not know if I can excuse them that just because they offer a challenge, sometimes. Edited by fateswarm - 7/12/13 at 3:14pm
