Sure is!
I decided to pull an all nighter after Ulduar 25 last night. Just was around farming Saronite in Storm Peaks, and Leveling my Pet Warp Stalker 'Agalloch' with the local worms/rhinos/harpies, all while spamming my rare mob macro to alert me of anything nearby.
After 3 hours of searching and farming, I gave up. It was 4 am and I logged off. Made some food, and looked at a video of his patrol route, nothing I hadn't seen before. Jumped back on, around 5:03 am, decided to give it one more shot, Figured I would turn up short. Headed from the Ravine, to the Blue Drakes. And as I'm spamming my macro, I get the repeated whisper of what I had found. My heart started thumping, it really caught me by total surprise. I was just going through the motion at that part.
Next up! The Power of......THUNDERFURY!
