It appears everyone's caught up with Deathwing (and with good reason), or at least I couldn't find a Blackhorn video that was up yet, though there's a few on the way. Since I had to miss deathwing testing anyway...

Pretty fun fight overall, though honestly p2 was a bit easy. Tanks took a decent beating, but that was it. P1 was pretty good fun though, and of our 6 or so wipes all but 1 were in p1, while the 1 in p2 involved 3 people standing in fire (are we supposed to hit that dragon?) and the tank getting meleed to death before the boss had landed.
