The devs speak Japanese, not English. As such they're going to post on the JP forums. The community team's job is to translate our concerns and relay them to the devs and to translate dev responses back. It could very well be that some of the dev posts are placed into areas of similar concern as our, and ours was the reason for the post. But yes, the devs aren't going to have to wait for translations of the JP forums.
Hey Crevox, did you ever join the REDDIT LS on your server? I saw you were concerned with just how much there was to udnerstand about this game, and they are very willing to help at all hours of the day. An LS like that would be your best resource for grasping this game.
