Are they worth opening? Because the drops from them from the previous 2 ToT events are completely worthless. Have anyone tried to lockpick a few from this event? Can you get anything special from this? Any help is greatly appriciated. So I can turn them in if it's nothing but a fancy container (and is the container graphic unique? or can you make something that looks the same with different name than "Chest of Heirlooms") Thank you.
