I was questing in Uldum and doing the quest where I have to sabotage the Schnottz troops' powder kegs, with Myzerian in dragonform flying around the obelisk. So he has over 2M hp in that phase, I was at 156k with Pandaria gear. I used the shrouding device and managed to sabotage one powder keg when he spotted me (like half a mile away). We stared each other for 2 secs and I start running and search for way out ohgod. Of course the whole place is such a hole you can only escape by flying. Wasn't long til the dragon cornered me and I went JUST DO IT while despe-retardedly smashing buttons and CDs. Turns out the piece of shit can't overdamage my second wind . With a big shit-eating grin I smack him across the cheeks left and right, and it turns out he wont go below 1hp. 20mins of running around with Myzerian scratching my back ensues while i fight off elite troops, until I finally get on the ledge surrounding the area and jump into the water. Victory was denied from me this day.
