On the fourth day of the second Sunwell Plateau gates being opened
there, the European guild SK-Gaming
has achieved the world-first kill of M'uru, the fifth SWP boss. Good job, guys! This is all the more surprising because I don't think of SK-Gaming as one of the big-name guilds, but maybe I've just been missing out. Edit: D'oh! That's the guild formerly known as Curse. I knew the name looked familiar.
Also, I would sort of have expected the US realms to get there first because their gates opened a day earlier. But on the other hand, Europe has been on top of the world firsts for a while.
You can see the loot above -- click to embiggen. That Shifting Naaru Sliver sounds fun.
