If they jump to max level without play, they won't learn how to play. You will have a DF fill of people who doesn't know anything because never played on low levels. Also is unfair for those who do everything and spent their time getting the level and unlocking all.

And then, come here, to the forums, to complain "How bad are the players!" and open 5642 threads about how they are ruining the game, and etc.

It is not only level, it's about learning process. There are people who never learn no matter how much low level shit they do, but most of the player uses that learning curve to progress.

So, sorry, but yes, new player should do ALL, like everyone of us did before.
