I've seen many posts about this subject so far, most of the original poster just saying "heroics hard, qq", however some have said they are "equalizing heroics" to make some bosses harder and some bosses weaker to make difficulty more consistent. I myself believe that the selected nerfs to the bosses far overrides the small amount of buffs to bosses. I also wish to ask the question of "If I did the heroics, as well as many other people just fine, what makes everyone else just so special?" True, I do not have a Volcanic Stone Drake as I really just didn't want to bother with it, but I believe sitting in full heroic gear/some raid gear gives me some credibility. I would like to see what the community thinks of these nerfs, and I want you to remember when you post the question I asked. Refute me if you wish, I will observe the comments to see what everyone says about these.
Edit: Also, no the end result of PvE is not to get to raiding. That is part of it. Raiding is supposed to be just as fun as heroics. If heroics weren't fun, there would be no reason to gear. That's like saying "Oh yeah leveling isn't fun, all the fun stuff is at 60!" to a new player.
