I canceled partially for similar reasons.

1. Random roller-coaster of class development
This is a major problem for me. My class' strengths can change completely in a single patch or expansion, yet a lot of longstanding problems (i.e. since nearly launch, all carefully tested and documented by multiple players) are often left unfixed. PvP also recently clobbered class development when Arena was introduced.

2. Arena
I had liked old BG PvP, however I loathe Arena. I also strongly dislike that the best PvP rewards require Arena. Honestly I wish Arena would just disappear. I know a lot of people like it, that's great, I hope they enjoy it... however I'm not one of them.

3. More accessible = more bland
As Blizz makes the game more and more accessible it gets more and more bland. We've seen massive reductions in gear complexity in stats and looks... but the result is that gearing has become an Ilvl hunt. It doesn't matter what gear you get. If it is a higher ilvl, it is better, and it will always look pretty much just as bland as the gear you had before. Raiding has become essentially useless except if you want gear earlier than other people, because Blizz has begun carrying forward badge and token buys as they release new content. There is no longer any pressure. If you don't complete your set of gear now, so what, in a couple months you can clobber some heroics and buy it... so you can just start replacing it again with the newest set. While I applaud Blizz for trying to fix the ever-moving gear window, I don't know if this is the best way to do it.

4. Balance pls?
The ideas of 'hybrid tax' seem to be going away a bit, however PvP vs PvE balance is a problem for me. The two game goals are so different and so at odds I'm not entirely sure Blizz can balance them together without separating them. PvE gear in PvP and burstiness is still a massive problem in PvP, and some classes and specs simply can't compete. Honestly I don't know how most of these ideas got out of testing and into the live environment.

5. Focus on quantity over quality
I really think the recent focus on releasing an expansion a year is part of the reason for the reduced gear complexity, enforced gear and raid accessability and homogeneity. If the game and gear is more homogenous and accessible, it is easier to create gear and balance raids and content. I also doubt Blizz will be giving away those expansions for free.

For these reasons, which were reinforced by the dismal class Q&As, I don't think Blizz's development of WoW is worth what I'm paying. if and when they turn themselves around and actually start doing things for the 'good of game' (as they so often like to say) I'll be more than happy to buy back in, but I honestly don't think WoW is in a good place, or is going anywhere good anytime soon, and I don't intend to pay them in order to play a game I don't find fun due to their oddly inept and random development. I honestly don't understand why they keep moving the product forward when there are major problems that need fixing. Sure the coders and art asset people are different, but wouldn't you maybe cut back on art dev and hire some more programmers to fix problems instead of ramping up the expansion release schedule?

I don't see how this is the same company that turned out the Diablo, Starcraft and original Warcraft games.
