I don't think you should go from lvl 1 to lvl 250, but leveling up should be a fun experience and one that persuades people to explore, in search of a better experience and more challenges, and that is only achieved when the difficulty level it is equivalent to item and experience rewards. But that a person late from lvl 80 to 100, on Luna from 15 to 30 hours, is an exaggeration and more if you don't have a good party. But that's only the people who like the game and have limited time think. Thanks.
