Having information available in the game itself is not a bad thing. I await the day I never have to have a wiki/database open.

And how is telling players "Camp Drybone is the Level 10 area, if you are Level 10 you will find things to do there" any different from saying "You go to Valkurm Dunes and fight crabs at level 15". If anything the former will allow people to explore on their own because they know that is where they are supposed to be.
