So instead of waiting 2 months for content, you wait that time to play an hour and then have to wait two weeks more for another hour even though that content is done and in the game.
Weekly releases of finished content sounds like a good idea if there is a progress bar to complete. A week of no progress bar and the previous bar amounting to no impact on the game at all is, by current experience, a really bad idea. Add onto that, every community event has been bugged or broken (save for Fractal Rush) with throw away rewards.
Just wait for all the content to be out and let the community progress bars fail.
Limited and timed content is the worst content ever, Living World 1 being prime example that almost bombed GW2. If Anet wants to come back to that, let them fail.
