Today being BlizzCon ticket sales day, Blizzard is anxious to keep everything running as smoothly as possible. In an attempt to lessen load on their web servers, they've temporarily disabled the Armory. In fact, this has been the case since last night, when I went to check out our main tank's armory after the raid (he had just gotten Shieldwall of the Breaker and I wanted to see what he was upgrading from).
This is going to be inconvenient for those of you attempting to form PuGs, especially PuG raids. Hopefully BlizzCon tickets will sell out relatively quickly, and this madness will be over, and our beloved gear-checking, snobbery-enabling service returned to us. How will you be vetting players in the mean time?
