I don't really mind it. I mean, it's not like new content is released every single day and removed the next day - making it hard for us to earn enough sellables to buy the stuff we want. It's not like that.
There's a lengthy amount of time before new content is released. This means that it would give us enough time to do jobs. That does not mean we have to waste our lives mining/fishing/woodcutting etc. A few weeks/months is enough time to allow players to save up their sellables. There's not much to do anyway.
