Would love to see open world dungeons reappear. Have stuff that cannot be designed for solo in the openworld.

But then again. WIll this negativly impact those who refuse to party? Remember the definition of a mmo is not playing together anymore. It is millions of people soloing around you......................(Insert alot more dots). If it hurts the lowest common denominator you cannot do it.

But seriously I think it would be a good idea. Just make it where the rewards are relevant and not all vanity and it would be an improvement to the openworld content.
