I don't know what to do or where to go next.

I don't understand the reasoning behind the zones. There doesn't seem to have proper quest hubs but instead the zones cover a wide range of quest levels that you're supposed to do several times. Am I right?

Even inside the "wilderness areas" and certain dungeons, there are more dungeons that require more level than its parent ones. Why is that?

Also, when using the LFG tool I use to join groups that I have no idea where are they. Sometimes the LFG party has a recognizable name (House X, market, etc.) but most of the time (I'm lvl 10) I don't know where is it.

Am I missing something?
