Apparently the RNG thought it owed me a favor, because I couldn't make this up if I wanted to.
Yes, I just got both the ZG Raptor and White Hawkstrider from Kael'thas in the space of three hours. The shock of soloing a raid boss to claim a mount I've coveted since 2006 had not yet worn off, and I wasn't even going to bother continuing to farm Kael'Thas after getting the raptor. But I had a half-cleared save (I'd bailed out to reset a bad group of adds on the third boss) and figured I might as well go for my fifth solo Kael'thas kill. The bird is listed at a 3% drop and the raptor at about a 1%, so the odds against my getting both back to back like this are pretty astronomical.
(And yes, I'm still thinking about my response to the LOTRO news. Turbine really overshadowed me on the blogosphere today. I guess I'm just going to hop onto my Hawkstrider and ride off to the top of the nearest hill, where I'll hop onto my raptor and ride off into the sunset. Also, I'm guessing that most of you hate me right about now.)
