This looks like the vault in diablo 3 treasure goblin.

But if this will be easy I am not seeing any good gear come from it and will be another thing to go to oblivion. Only thing may save it is in case some mats dropped there are exclusive like diadem.

Tbh, they should spend their time in doing something more useful, we have a lot of casual play and barely endgame options every patch.

Still praying to them release the 8-man dungeons like 1.0 were and being endgame instead faceroll content. My hopes are in 4.0
