Grim1: You are patently wrong with your last sentence, which I have to assume at this point is pure hyperbole for the sake of hyperbole. Shitty groups can and do wipe all the time in just about every game on the market. Just like good groups can and do steamroll content in every game. Just like in EQ. The difference is, messing up in most modern mmos doesn't mean someone else takes your place and you are fucked out of content. It generally means that you just have to get back to where you were and try it again. The difficulty is not all that much lower, the nature of the difficulty has changed though. Now the fights are (across the board) more technical, even in the most bland WoW-inspired game around. The penalty is just less other-player influenced.
AE groups existed in EQ, and while they are more common as opposed to being the playground of wizards mainly, still the best way to get xp/aas available. It just so happens that most people having access to a better method of killing stuff make use of that better method instead of the single-pull-only method of crawling through content.
