Last night playing in Wabba we were defending Sejanus outpost and the Emperor used Dragon leap to jump on me followed by Burning Talons and Spiked Armor. Then ran past me to get more damage done.
I threw a negate on him and used Destructive Reach to throw him down on the flag where the Mages finished him off promptly. Just saying beware of the flying DK Emperors. LoL
