I've noticed it too. It's a pretty cool feeling.
I think the reason why is that A. We haven't had a new release of anything in a while, so there isn't really a lot to debate and argue over, and B. Most of the heated topics of the past (like KCs or OP characters) have pretty much become dead horses that no one feels like beating anymore.
As a result, the community is turning to more idea/suggestion threads and giving each other tips and support. There's a general sense of optimism right now as we await what's coming for this game in the future.
