At the moment lvl 75

If your HARDCORE and have alot of money, you can lvl 1-50 in a week. But for the average person at least 7 months of so, i just got lvl 50..and i am totally unequiped and i am so going into getting more equips, now thats because i didnt have an advanced job too..if i did, prolly be way longer.

As for lvls beyond that, way longer...take your tiem and enjoy everything thats all.
