There's a lot of the usual stuff that you hear from guild after a big down, but there's a few new things in there, too -- apparently SK and other raiding sponsors are actually paying "premiums" for world first kills. Doesn't sound like a lot, but they do say they'll be able to do a meetup this summer thanks to their run in Sunwell, so that's a fairly substantial amount for playing a game. Both M'uru and Kil'jaeden are on their top 3 encounters in the expansion, along with Magtheridon, apparently. And the Sunwell "gates" system gets a pretty good review -- SK says it kept some guilds going even when they might have been burned out on the tougher fights.
All in all, an interesting interview. They dive into drama a bit when talking about the friction between SK and Nihilum, but mostly, they just stick to what it's like raiding as a professional guild in the Sunwell. It will definitely be interesting to see how these kinds of guilds react to the 10/25 man change in the expansion -- raiding has come a long way from the 40-man runs in vanilla WoW, and these guilds may have a lot more competition for the 10man world firsts.
