Actually, he didn't confirm whether or not it was human error. He was very careful in his word choice, saying that it could possibly be his fault, or perhaps he was never given the information to relay to us in the first place.
That way, to us, we can say it might not have been his fault. And to his superiors or whomever, he can say, "Look, I never actually blamed you. I said it might be my fault." He's placating both sides.
Honestly, if you think about it, if he's being withheld information, it would be therefore impossible for him to know whether or not it was accidental. Because in being unaware of the information, how could he know why he wasn't?
Well when i said "human error" I meant that as a blanket statement to cover all of blizzard. dax seemed to imply that a compound of very small errors added up that led to this situation. I wasn't trying to single out the CM.
"Human error" isn't the reason things are left out of the patch notes unless we are all expected to believe a company the size of Blizzard has nothing resembling a quality control and internal documentation process.
Every change is known and tracked and if something is left off patch notes, it is more than likely by choice, if not by design.
Sometimes I suspect it is because they hope the change will go unnoticed and if they see that it is they adjust what is changeable back before there is "proof" it changed at all.
But to suggest that some chain of human error led the myriad of things that failed to be mention in the patch notes is preposterous. They find it acceptable because their customers as a whole tolerate it.
While it never had the playerbase of WoW, the developers at Everquest had the same "shh, we know best" attitude. Eventually though, there is an expac full of "we know best" that comes along and you can find 80% of your players gone.
EQ did it with ONE expansion that was virtually unplayable and even where it was playable was just not fun. Kind of like dailies, and gold gold gold slot machines and eternal gear upgrading and an overall expected increase in time commitment to play the game like we did for the last 3-4 years.
My playstyle doesn't totally conflict with Mists, but I can't see being entertained by it even as long as I was by 4.3. I just don't have the stomach for doing Golden Lotus again even with the rep doubling.
Mists just plain sucks the fun out of the game by sucking away way too much time demands and if this doesn't change, it's gonna make the Cataclysm bleed look like a paper cut.
TLDR: They don't release full patch notes because they think they don't have to because they believe, like many forum posters, that no one would EVER quit. By the time they learn it doesn't always cycle, sometimes it just goes down, it will probably be too late.
