It's an incredibly boring way to expand an MMO. It doesn't feel like the world is expanding but rather than people are disappearing in their own rooms where there's just a typical level.

It's basically just designing a co-op mode to any game while completely ignoring the potential unique to MMOs.

Nice going SE. It seems they created this to combat the lag issues of the current online infrastructure but are sticking with it even when the new system comes around. I'd be fine with it if this game was called Monster Hunter but it's not. This is not even the arcade-like crystal chronicles but I guess those values flew out the window about 5 years ago.
