From a design perspective the biggest issue is that LoV is just too inaccessible. Having to be in spot without being able to do anything in the meantime while waiting is the antithesis of good design.

I know that this is done because they want to have it make sense, you wouldn't just starting playing cards without being in the same "room" after all, though when these systems reduce the players ability to interact with the systems, that is malicious design. It's trapping the players if they want to participate, but cannot find a match, which brings up the second point that a lot of people have already brought up.

The GS games needs to have a duty finder that spans the data center. These minigames thrive on community and having a lot of people participating is essential. By restricting it so heavily they basically made the system D.O.A.
