My guild does voidreaver kinda easy but to improve progress and have more time on other bosses we use a little exploit.
What you need?
A priest in the raid, prefer a shadowpriest since they got +hit to avoid resists on mindcontrol.
Step 1: Invite shitloads of hunters and rogues, to your voidreaver raid.
Step 2: Mindcontrol a Tempest-Smith (
http://thottbot.com/c20042), in voidreaver his room.
Step 3: Engage void reaver with the Tempest-Smith, and do a abillity on him that reduces the armor on the target this target would be voidreaver.
Step 4: Have free loot.
Record of killing voidreaver is now 53 Seconds.
This is still not nerfed since i did it yesterday.
Some other guild did it to:
