All the Warcraft news has shifted to Patch 6.1 which is on the PTR now.
And let's be really clear up front: This is not a "content" patch. This is a "fixing-things" patch. This is a "roll-out-the-stuff-we-should-have-had-ready-at-launch" patch. Fixing things is always welcome, but I would have expected that in a 6.0.X patch, not disguised as a content patch. I can't begin to explain why things weren't ready at launch except to guess that a lot of the things (like how they've aggressively expanded the garrison missions) feel like they realized somewhere in the past three months that the basic content they rolled with wasn't nearly enough.
Warcraft subscriptions bounced back from continuing declines as
Warlords of Draenor came out to levels that we hadn't seen since... well, the last time we left Draenor, in the
Burning Crusade. I'm not sure if that's because the playerbase was jazzed about seeing proto-Outlands, or if that line-up of smug looking orcs on the box cover was just so exciting, but it's something worth considering. Unfortunately, Blizzard cannot expect that subscription trend to continue. Endgame hasn't delivered, and Patch 6.1, which, again, is not a content patch, is not going to deliver either.
What's the problem? Always an easier question to ask than to answer, but here's a few observations.
This expansion has already had significant systems overhauls and that's just continuing.
Some of this, like the garrison, has been a remarkable achievement. Some of this, like reagents tabs and toy tabs and heirloom tabs are large quality of life changes and probably required intense amounts of coding but don't feel revolutionary. Now, Blizzard correctly points out that the guys who figure out how to hang our heirloom items in their own tab are not the same guys who design five-man dungeons, but there has still been an historical tendency for Blizzard to largely focus on systems or content but not really both at the same time. They don't release one without the other, but one is always dominant when they push code out. I think the systems overhaul, and the many serious problems that arose and had to be dealt with has taken priority over "content" to a certain extent. It may have had to be that way, however.
