So this is my latest find, I was not sure where to put it so I will post it in the Exploit section.
I was out farming quests in netherstorm on my rogue to get some cash for epic flying mount. I am Aldor so I got a quest from the Aldor quest giver in area 52 called "shut down Manaforge B'NAAR". I already knew what to do on the quest since I had done it on my warlock. So I just went there and got the key and then started the quest event. When the mobs started spawning I saped one mob and then I noticed that when I saped another mob the last saped just stood there and did nothing. So I continued to just sap and after a while the mobs just despawned and I cleared the q without doing anything but saping.
This is confirmed, I have done it on every single one of the quest followups rly gr8 for the lazy boy who doesn't want to kill mobs without getting any loot.
I couldn't find anything on mmowned like this so I guess its new. remove it if its a repost.
Cheers!
