Back in july I honestly thought they were getting more open about balance, at least once every 2-3 months, but now we're in november and there's still silence about one of, if not the most important aspect of the game.
I expect more than just some change to be coming with the next living story episode, but the good thing about last time was the posts Anet made before going through with the changes.
And no, the fact many people complained right after they saw the changes does not justify the silence. Being hard at work on living story/ new xpac does not justify it either. Basically there's no justification for writing a couple posts every now and then to show in advance what they're working on... assuming they're working on it of course.
I'm not demanding anything, but it is quite sad that they ditched the whole "be more transparent" thing
