Obviously, Blizzard knows how to design a game, so I'm not suggesting we *need* to be heard. However, I think everyone wants to feel like their feedback is being heard -- even if it winds up being disregarded in the end -- and honestly, I actually do think it's important to get the outsiders' perspectives, as well.
Also, please don't take this as me suggesting you guys aren't doing a great job -- it's more that I feel like we tend to see more "PR-responses", like Blue posts go through some kind of robotic-filter, when sometimes (as is the case on the D3 forums, much of the time) I think it's better to just have more casual posts, more direct conversation than deflections or "official responses".
Anyways, that's just my perspective, but I think it'd be nice to see a tiny bit more interaction with the community. Maybe more Q&A's, comments on player suggestions, stuff like that. =)
