I think I remember someone once posting that Blizzard had good communication with their player base. I mean... just lol.
I go onto the reddit for a much smaller game like Runescape and there's are posts from official mods posts all over the place. Actually posting replies to people and the questions they want answered. Meanwhile on the Blizzard forums, I doubt you could even average a single Blue response a day. And when they do show up, they probably aren't going to be talking about the issues people want to hear about.
Take a lesson from Runescape. Even if it's nothing more than a reply saying you passed their idea/bug fix along to the proper people... for something they already knew about in the first place... just do it. It doesn't just make the player feel valued, but actually proves you are there listening to them.
