What we're some of your mistakes with MapleStory when you first joined?

When my best friend and I were first starting out and had both installed Maple

"Come to Bera!"

"... there's no Bera here. D:"

Turned out I'd signed up for and installed MSEA instead of Global. :B

Favorite answer so far. Myself; I started as an assassin and later quit it as I found them ludicrously boring which of course had its stats were naturally messed up with str & int. at some theif items giving/requiring Str.
Should've thought more about what I wanted to do in the game before starting...helping others namely.
