There are a couple of hazards of being a blogger on this side of the pond. The first being that, when you consider one of the largest raiding guilds currently tearing through raid content is in the EU, there's quite a bit of time lag between when they take bosses down and when I sit down to run news postings. The second thing is that in the case of a guild like Nihilum, they've trained on the PTRs for quite some time and are thereby completely ready to tear through these fights and rack up the official Live Server World First kills in nothing flat.
This said, as if to answer my progression post yesterday, Nihilum returned to Black Temple on the heels of their last string of accomplishments and took down three more bosses. First they turned their collective might toward Teron Gorefiend who dropped some quite tasty goodies. From there, they chewed up Gurtogg Bloodboil and spit him out. (again, not without snagging some sweet loot first!) From there, Nihilum headed for (and successfully tore down) the Shade of Akama for lots more nifty purple goodness, and another live server World First. While they did not finish the Essence of Souls event (pictured) they are hoping to return and knock that out in short order.
Now some of the reactions I got in mail the last time I posted a progression post for Nihilum raised an interesting question to me. If a guild goes on the PTR and learns the strategies there does that somehow lessen their world first accomplishment on live servers? It seemed like several people felt that the accomplishments were diminished due to having been done prior on the PTRs. Personally, I've got mad respect for those who blaze the trails -- whether on the PTRs or on Live servers, although I am nostalgic for when it was a bit more of a surprise as to who would do so. (One of the few downsides of the job, I suppose. heh)
