It really is only an additional month. I am not worked up over it, especially since a lot of games are coming out in October (Dragon Quest Heroes, Legend of Legacy, Tales of Zesteria, AC: Syndicate).

The amount of content put into 3.0 was not the issue. Technically there is a lot to do. It is the quality of said content I come into question. Average players don't like Savage Coil and everything else is face roll easy to the point they are bored with it now. In turn also some have less motivation to do other content or level other jobs. Right now you either go very casual or hardcore, there is no middle ground.

You can put two or three things only in a game and make them last a long time if made well.

Also, yes developers do need a vacation. Just like you need one from your job once to twice a year. It is just one month over the intended schedule, and they did say first 10 days of November. If you are truly bored with the game, entertain yourself with another game. Unsubscribe if you want to not pay for just October.
