mayb to make sure high lvl people wont rape weaker people, mayb there should be a lvl restriction or so. That is area A you can only fight people between 2 lvls lower and 2 lvls higher (lvl 1 could ight lvl 1, 2 and 3, and a lvl 55 could fight a 53, 53, 55, 56, 67)
And on other area\'s, that are harder to reach and where stronger monsters are, there also are lower limits, like fight between 15 lvls.
