The retention rate of newbies is really low, so there won't be many low leveled people playing. By the way, are you playing in Crest or Folrart? Because I've seen lots of people who are less than level fifteen in Folrart, and they should not be there. I don't even know why they are allowed in anyways, they will just get stomped over and over again and give up because they get frustrated.
The Crest Arena is there for your protection! Use it!
When the end comes, and enemies are rushing in from all sides, I will be at your right hand.
