Open world content...

[Jynx]

There s nothing that has genuinely been presented to us which indicates that 2.0 will become a lobby, or anything close to it.

Not to be blunt but pretty much everytime Yoshida tells us something new about the game or releases content it ends up in a instanced event.

So I don't get where you don't see where the concern is coming from. All we have to go on for hopes of open world content is they don't want to waste the effort of making new maps. But with comments like exp-parties "Not going to work" in 2.0 I find it even hard to guess what the point of the open world will be besides farming.
