Without a Trace

Talked to a gm about this short chain and of what i got to an answer it sounded it was bugged.
But if it's true that eviloni said that this quest chain was removed in beta im gonna be cranky, really wanted this quest reward...

After speaking to a GM this was the reply I got regarding this quest. So if anyone is looking to finally put this to rest and give up on the legs (For Alliance at least) this is it:

I had a look for you and this quest was only in the beta of Mists of Pandaria it was removed and the chain stops after the quest called Hozen Aren't Your Friends, Hozen Are Your Enemies which you have already done.

There were two quests after this called Explosive Evidence and then Without a Trace which were removed for unknown reasons to me. The only way to obtain the legs would be to faction change to the Horde and do the quest called Acid Rain sadly. Which might be a bit too much for just these legs.

The quests might be added back into the game at some point but at the moment this isn't sure. The devs are aware of it though and are looking into it. :)

So there you have it! Epicly disappointed that my Pandaren Monk can't have her rogue legs! But here's hoping Blizzard fixes it in the future!

This quest, and several others, was removed during beta when Blizz redid the Jade Forest intro.
