But, they should be realeasing content for the time you are paying and they are not.
That's not content., Bug fixes is not new content.
I don't care about WoD, If Im paying now I should be receiving content ...welll... NOW...
There's no need for that, other games have proven time after time than content can be develop and released faster.
You just have to open your mind and try new games to see how you are being lied about development time by blizzard.They hook up people with vague promises, I don't understand why people have preorder WoD withouth even trying the beta, there's not even an alpha yet.
--------
F2P games have proven that content can be released faster, for example Gw2 release new content every 2 weeks of so, and Blizzard have been promising for years now that they would release new content and that expansions will come faster, all has being only lies.
With that said, I don't think Blizzard urgently needs to bring more content, but to make old content playable and fun again, they can do it with the technology they use to reduce your gearscore, imagine doing Ulduar again at its level, or if Mop is your first expansion to raid all the other raids you have missed at the level it was ment to be.
