The game is way to Easy until you get to End Game

At the fan Fest they mentioned something about players Entering a Code and you could start the game right away as a LV50 DRK.

I didn't understand it that way. From what I remember he said you'd register the game and be able to be a Dark Knight right from the start but he never said you'd instantly be level 50. They meant it more as an explanation that you do not start as a class and then unlock the job at lvl 30 for this job.
