Strange patch note choices (or, my last Orc shoulders post ever, I swear)

I can confirm for you that yes, patch 2.2 has finally fixed our Orc male shoulders. Finally, my Orc Shaman can hold his shoulders up proudly (ok, well, a little hunched down under all the weight, but still). I know lots of you readers are tired of hearing about it, but the saga is over: our Orc shoulders have grown back. Now I'll never mention it again.

Strangely enough, however, this change didn't make the patch notes, and when players ask why, Neth sounds a little tired of talking about it herself. She says that while the change did not appear in the official 2.2 notes, "one graphical item of which has been stated as being fixed many times now, does not make it less accurate." I've wondered before who exactly writes the patch notes, and yet again I find myself wondering what the method is behind their madness. Some patch changes, including some boss tweaks, are clearly not included on purpose. Some huge changes (like the DOTs affected by resilience change) get the smallest of mentions. And some small changes very much awaited by players, like the anti-AFK measures, get quite a bit of ink.

Now, I doubt that Blizzard purposely left the Orc shoulders change off the patch notes-- they probably just didn't think it important enough to include. But surely there are things that they do leave off of the notes on purpose, and some things that the devs might not think are big, but that whoever writes the patch notes chooses to emphasize. Whatever their method behind the madness, I can't see what it is at all.
