You and the normal people will go sleep, I know that. But the netge-otaku people won't and they're the kind of people who drive 2ch forward, no ? ;)
No, not really. 2ch is a lot more diverse than that! Also, the majority of people who play MMOs, at least the people I know, still have to go to work in the morning.
Besides, the problem lies with SE and their shitty server(s?), no? Not the Japanese public, so need to keep picking on them. There are loads of other MMOs that can apply expansions and patches seamlessly and have much more subscriptions than this one.
