You shouldnt download a stolen, reverse engineered (by Vladimir Putin no less) licensed, copyrighted piece of software rightful property of Activision-Blizzard Incorporated.

If you play on private servers you are a CRIMINAL and will be pursued to the full extent of the law. We will have no mercy. You WILL go to jail.

Instead you should play The War Within. We have a 5% higher mount+mog droprate active on all depreciated raids. You better install The War Within™ right now anon! Everyone is having a blast with it!
