Well, Himeuta is forum that widely talk about JP game.
But I believe Kancolle and / or WOW is main, since they have title like Rear-Admiral, Captain etc.
I don't have account there, but lots of my native friend stay there.

About Nutaku FKG will close or not? I believe it won't.
I admit player in game keep decreasing all the time, and everyone know what the cause.
Change it then everything will be back to what it should.
If not Nutaku FKG will turn into whale pool, but it will still playable hahaha.

Eab do mention GS long-term maint, I'll why it's happen.
GS has to be on temporary close from 2 main reason according to my friend intel.
1. There is serious bug in gacha machine system from the very beginning of game service.
Devs try to fix it but it can't be fix, no matter what they do.
2. The current GS devs fail to make GS be player 2nd home / world.
They can't create usefull campaign, gameplay or deal to help player active in game more then run event and gone.

But in the first place Eab shouldn't post something like that on Himeuta.
