Ask Reinhart just how much more gets posted in the JP threads from the devs than the English ones, looking over everything he's translated we get about 1 post for every 3 they get even though we have the exact same topics over here(some of which are just as high profile to all countries and not just Japan).
That's just because the devs speak japanese, so it's much easier for them to communicate. That does NOT however mean that stuff doesn't get read on the NA forums nor does it mean that our excellent community reps don't communicate any of our concerns to them.
