Bored w/ nothing else to do, so a group of us went back in to Ulduar to play around, and picked up 2 fragments off of 5 bosses. Historically our luck was to average maybe 1 fragment every other week out of a full clear (excluding the guaranteed one off of Yogg).
Anyone else seeing more of these dropping, or was this just unusual luck of the draw? I'm still 15 short to craft Val'anyr, but if they're dropping that much more I'll probably grind for it more.
