As you might have heard previously, the Underground Kosmonavts of EU-Ravencrest scored the World 2nd kill on the 10-man version of Algalon. Shortly after their kill they released a video of it, which has burning across the net. Algalon has been incredibly hyped, so it doesn't surprise me!
Now, I haven't done this fight, I won't pretend I have, and all that I've seen is this video, so take this as, essentially, me talking out of my rear end: This fight looks really easy compared to what I've seen of Ulduar so far. Quite honestly, it looks like a tank and spank compared to something like Mimiron. Not to mention his hard mode, which you need to do to get to Algalon in the first place. Maybe Algalon is Ulduar's Brutallus? Hopefully there are elements to the fight that don't show up on video very well (from the point of view of a Hunter especially), and what we're seeing isn't a good indicator of the whole encounter.
Of course, I really don't mean to trivialize the accomplishment here. These guys were the second guild in the world to down him, and I imagine that if it were as easy as the video makes it look, a lot more guilds would have done it by now. Great job, Kosmonavts.
