Just in case anyone reads the original comment and thinks it's accurate, it's not. I'm not sure if the poster dislikes WoW and just likes to trash talk it, or if he's never played WoW and is speaking out of ignorance, but basically the comment couldn't be more wrong.
The term "hardcore" does not have anything to do with absurdly grindy loot rules, or anything of the sort. Hardcore refers to the game mechanics, and to how tightly tuned the boss encounters in the game are. A "hardcore" MMO is one that would require to min-max your character to get the most damage/healing/whatever out of it, to get the best gear available to you, and would give you very little margin for error during the boss fights. It is this last point which people usually point to as an example of player skill. I think it would be fairly self-evident that overcoming whatever challenge the boss encounter throws at you while not making any mistakes must surely require some manner of skill, no? At the end of the day, you're playing for the challenge. If there's little challenge to the boss fights, they're less fun.
Contrary to the assertions of the OP, the prestige associated with certain hard-to-get gear is not the fact that you have "be very lucky on the rolls", but in the challenge associated with the boss fights. In fact, as far as I can tell, the first five paragraphs of that post are literally flat-out lies. I have no idea how it's been modded +5 interesting, since it seems to be pretty much entirely a troll to me. Bosses in WoW have never dropped only one piece of loot, even at release, when the game was considerably more hardcore than it is now. As others have already pointed out, WoW was never as hardcore as some oldskool MMOs like Everquest, and it has been made considerably more friendly to casual players over time. New boss encounters have consistently been tuned to be easier, and are considerably more forgiving of mistakes. WoW has actually done an excellent job of catering to both the casual and hardcore crowds. There are still some boss fights that are quite challenging, and beyond that there are even optional hard-modes that give extra rewards.
As to the OP's claim of "[The hardcore crowd] get upset when normal people with jobs and responsibilties can get as far in the game as them. If everyone can achieve the same, then they are no longer special." This has never been true. And I'm speaking here as a non-hardcore player. It took me the better part of two years to get my character to level 60, for example. The argument has never been about "getting as far" or "achieving the same". In an ideal game, everybody with the skill to succeed would be able to make the same progress, see the same content, get the same loot, regardless of if they have a busy schedule and only have a few hours a week to put into the game. The complaint that was made comes about because the players themselves (and I mean pretty much all the players, not just "hardcore" players or whatever) use the level of gear as a measure of the players progress. The problem was that a few years back, it was possible to obtain the top quality gear without possessing any skill, and in fact without any input of effort in the slightest. If you need to group with some people to accomplish something in the game, it helps to know if they're competent, right? Well, there are few enough ways to tell this in a game like WoW. Previously, gear could be used as a sort of check for that. But if everyone is wearing top of the line gear, you might bring along someone on the assumption that they're competent, only to spend hours fruitlessly banging your head against a wall. Thankfully that situation was eventually remedied, and the complaints have been significantly quieter since.
The OP has gone to significant lengths to try to portray the hardcore crowd as nothing but whiny kids. In fact, some of the more hardcore players I've known have been adults in their late 20s and early 30s with lives and even kids of their own. These people have never said that "WoW has failed because it only attracts the kiddies". Why would kids complain about WoW attracting kids? Another lie by the OP, methinks. In fact, the hardcore players merely said that WoW was not the game that they wanted. It's a perfectly valid opinion. And it's undeniable that WoW has been courting the more casual players. Different games for different people. It's never about the loot or the in-game rewards. It's about the challenge of playing, and having fun. Some people like a game with a little challenge.
