Destruction Derby

Destruction Derby is bugged for alliance players ~ you can get the achievement with a little exploit... You have to destroy the 'Siege Engine' within a duel with your friend you and all players nearby get the achievement. 1. Get Rank 2 2. Build a Siege Engine 3. Exit the Siege Engine 4. Duel a friend 5. Get into the Siege Engine 6. Let your friend destroy the Siege Engine Even the player who is sitting in the Siege Engine will get the Achievement. So have fun. ;-) Found this info on a site I read

Is it currently bugged? Me and my friend somehow can't get a credit for the Siege Engine...

Duel someone in party (this way both get the objective for the "Wintergrasp Siege Engine"). Make sure you have a Siege engine close by! One goes in the Siege vehicle and the other guy destroys it -tada!

(The Alliance can not get the Siege Engine objective -I guess Horde can for downrating. Alliance players will notice that this fixes the issue. 308 patch I think they also fix this bug.)
