i had never heard of anybody farming di this way before, so... maybe this will help some people out ;)
this is ROGUE ONLY btw, there's no way for a druid to do it. you'll see why near the beginning. prove me wrong if you wish ;p
i don't care if you don't like the music, mute it or something then ;p
also, yes i know that you can't ACTUALLY farm 148 di per hour this way, but that is the rate at which it was farmed. can't reset the instance that fast. i'm not 100% sure what the reset timer is, but generally once my hearthstone is up i'm able to go back in again and get more.
p.s. the file got slightly screwed up during the upload, but it's still playable. it just freezes for a couple frames during a pretty unimportant part..
