Nihilum, everyone's favorite (okay, some people's favorite) guild, would like us all to know that they plan to come back and world first the Sunwell Plateau the way they did Illidan. Apparently since putting Hyjal and the Black Temple on farm they've, well, been farming them and PvPing and taking more or less a 'holiday' away from the game, which makes sense, insofar as they don't really have any new content to see. Sure, Zul'Aman, but when you've already beaten Illidan going back to the ten mans is kind of anti-climactic. So they've basically been done with WoW. But they haven't actually stopped playing, so it's not a comeback, they've been here for years.
Yes, I made an LL Cool J reference. I went there.
They've also redesigned their site if you intend to make use of it to keep track of their progress: I have some old friends back on Norgannon I know will be watching them intently. For those of you who won't, well, it's still a very pretty site design, and you can always watch this Babe Ruth like 'calling' of their eventual success and discover with us all if it's genius or hubris.
