Issue with Rogue Quest klaven's tower

So it would seem that you can’t pick pocket unless you have the Master of Deception talent. Is this a bug or are you only allowed to use pick pocket if you have Master of Deception? If this is not a bug, and you have to get the talent then how come the quest is open no matter the spec for rogue? How come it does not tell you that you need the talent in order to complete the quest?

I ask these questions because if a player did not spec into the talent first they can’t complete the quest. I know this because I am on the quest, but I didn’t choose to spec the talent. Because I didn’t Spec into the talent I can’t complete the quest. I have tried every way I can, but I can’t pickpocket unless I spec into the talent Master of Deception.

So If this is not a bug then are you going to update the quest for the next poor soul that didn’t spec the talent? Ether way I have a quest I can’t complete because I don’t have the talent, and I can’t use the spell pickpocket at all.

I was able to pickpocket without Master of Deception but I have Stealth Rank 2. So it might just be a matter of having better stealth or being high enough level to lessen your agro footprint.
