Time Sage, Hourglass dungeon(cannot be found in current game :c), Saloonbot Mayor

DOES ANYBODY REMEMBER HOURGLASS DUNGEON?????????????????

It was my second favorite dungeon in the game(most favorite one is train station dungeon, I don't lie), but it disappeared all of sudden :( last time I saw hourglass was- like, before MOP patch? IDK :P

I hope devs bring back the hourglass dungeon :3
