Nostalrius Begins - Quality wow vanilla realm (1.12)

Warlock quest chain from Impsy in felwood available to do? I would really like to get the staff from the last quest.
I only got to do "An Imp's Request" after that there were no more quest on impsy.
Is it bugged or is it on an other patch? Is this patch coming soon if thats the case?

Where did you start the quest An Imp's Request please? because I cannot find it anywhere.. (I'm a lvl 52 warlock)

The rest of the Sunken Temple Warlock quest comes in a later patch.
