Maybe I'm just ignorant of the reason here but is there any reason that the absolute full list of changes in a patch are not listed? For example, the stealth nerf to Spectral Guise, the change in pvp power as it relates to healing, etc. were not mentioned. Most of the times people have to find these out for themselves then wait for confirmation on their respective forums.
I compile the notes, so I should probably explain a bit.
Essentially, the development of every World of Warcraft patch is a highly iterative creative process. Like most creative processes, there's a little bit of chaos involved, with discreet sub-teams working on individual projects, but also coordinating closely at the same time, so there's always a frenzy of activity going on at any given moment. With that in mind, there's not one comprehensive, monolithic source of information on what's being changed. Instead, information needs to be solicited, provided, re-phrased, confirmed, re-confirmed, edited, and revised as the patch is developed and I compile the notes. That also means that if there's an omission, you can be reasonably certain that it wasn't intentional. It's also worth noting that, as the code changes to resolve issues and implement new features, sometimes things go unexpectedly wonky with older parts of the game.
I'm careful to compile the notes as completely as possible, but it's not unlikely that some things will slip through the cracks from time to time. Perhaps an item didn't follow a typical development pipeline, or something was fixed at the last second. And of course, there will be rare occasions when I simply make an error and omit something that should have been included.
In all cases, we try to make the notes as informative and complete as possible, while also keeping them relevant for 99% of players.
Because if they detailed everything that went into a patch it'd be about ten pages long and everyone would whine about that. I agree that they could be a touch more extensive though.
That's not precisely the case, but we do try to keep things relatively concise. Admittedly, there are many changes that occur that wouldn't mean anything at all to 99% of players, and really crunchy notes of that sort have historically always been omitted.
They do not mention the ones which are apt to upset a large majority of the players.
That's not the case either; there are notes in virtually every update that we know will upset someone
. We don't shy away from providing information that needs to be provided, and I'm afraid that you are ascribing a motivation to an event that is actually happenstance.
