My friend just showed me this video where this guys with a 15-man raid and he jumps in the lava by the great anvil and queues them up for Arathi Basin realllllly quickly. The video fast forwards to Arathi Basin ending and then the rest of his group falling into the lava and dying.
Being that I play Horde... I figured out how to do the same thing.. go to the top top top of Org and jump off and queue the mid-air , as soon as ab ends everyone starts in the spot where you queued (mid-air) and plumets to their death.
this will definitely get you some sort of punishment for griefing, if your caught... i use slow fall so i can queue up from the top and i don't die.. very very evil.. I KNOW
