I disagree. They may not discuss it with us, but they undoubtedly discuss it amongst themselves. They may take what they balance next into consideration based on what the community wants. Also, you can't have knee-jerk after month long discussion. That's a contradiction. They may balance with a heavy hand (or hammer) but they don't just change the stats on a whim or at random (usually) but never on a whim. Or at least, as far back as I can remember. Just because they don't balance things the way we think they should, or in a way that pleases us, doesn't mean it was a knee-jerk reaction. They take their time, and that's far better than rapidly. At least, in my opinion and how other competitive games handle balance as well.
