Sour grapes?

The biggest actual complaint here is not that they got world first but their attitude towards it. Who gives a shit if they "beat" wrath? Grats to them. As most people here have said, we're still levelling and having a blast, and I'm sure when we get to those raids we'll have fun too.

The issue, and it's something we saw from Nihilum in TBC as well, is this attitude that Blizzard should be catering specifically to them and to a lesser extent the other top end hardcore guilds. "Worries" that are thinly veiled posturing, complaining and chastising Blizzard because there's nothing left for them to do, even though the vast majority of the playerbase is still progressing happily through the content

These people make up a tiny TINY fraction of the playerbase, and are not the people Blizzard should be focusing on.

So congratulations to this guild for their accomplishment. I'm sorry that you found it so easy, but realistically that complaint means nothing to 99% of people currently playing the game.
