Just to throw in my two cents... "We've received reports of [name a couple things that were reported] and complaints about balance, and we're currently looking into it." would have been a pretty simple baseline response to the immediate reactions of "everything's broken" that cropped up, and I believe would have swerved a good bit of the community's frustration about how poorly things have rolled out.
Going absolutely silent through days of mass complaints and annoyance with the knowledge that it'll all be addressed in a future update (that nobody in the fanbase knows is coming any time soon, if at all) is effectively doing nothing from a community management standpoint. gnomegates (and a dozen other people) said it best.
I know you're busy but just saying "I've seen this and I'll look into it" before is more effective than saying "sorry for the silent wait. Yeah we heard" after, and doesn't seem like it'd take a whole lot more work to post.
