Changing gears a bit, figuring this would likely be the optimal place to ask right now.
I'm still in the middle of farming my Fragments of Val'anyr from Ulduar25, as I've been soloing as Guardian for a little while now. However, since 5.4 was released, I haven't had any fragments drop at all, even while doing hard mode versions of encounters. Due to time constraints, I haven't been able to do a full clear, but clearing usually 10 bosses a week should at least yield one fragment by now. Has anyone else collecting fragments not had any drop since 5.4?
