I love this post on the EU forums: Ahjua complains that as a casual player, it would take him months to grind the items, find the groups, and get the gear necessary to unlock the new Death Knight hero class. With a social life that only lets him play a few hours a night, he'll never get it all done!
Whoops, except that the quest itself hasn't even been invented by Blizzard yet. They haven't said that it requires rep, or gear, or running instances, or really anything at all. We know absolutely nothing about it, and yet this guy feels the need to complain that it's already too hard.
Hopefully, he's just joking (if not, maybe he's just misinformed). But just as I've asked for patience on the PTRs, it's important to realize that everything we heard about this weekend is a long, long way off. In fact, I almost wonder why Blizzard released it so early-- if they've got Zul'Aman, voice chat and guild banks, another raid instance (probably the Sunwell), and maybe even another 5 man coming out before the expansion, why are they trying to get us all excited about Wrath of the Lich King? It's OK to be excited about the new expansion (I am), but it's not OK to pass final judgement on something that hasn't even been created yet. Let Blizzard do their thing, and then when we know details about the quest and what it actually entails-- then it'll be completely fine to complain that it's too hard for casuals.
