Damn, what server do you play on? Only one guild on my server has even cleared to Yogg-Saron.
Stormreaver. By most raiding guilds, I really only meant like the top 3-5 guilds. The rest are just the typical scrub guilds that die every other month, and come back with a different name, heh.
Impervious, like a highly ranked in the world guild, cleared it yesterday, I think. One of the other big guilds cleared it today. The guild I'm in got pretty far from what I heared. I don't have a 25 man raiding spot, though. =\
Edit: Yea, Impervious was 11th in the US, but I don't think wowjutsu has been updated very recently.
