Service End

Is it ending soon? I've been playing since launch, but it ended up feeling mediocre. Events just kept alternating between exchange events and ranking events, and only at the very end did they implement a half-baked system to help out with overflow characters, something people had been talking about since release. I played quite a bit, but there were many parts I wished they'd fix, and I wonder if they could have extended the game's lifespan a bit longer if they had taken action sooner.
