That all depends on your class, your funds, and your knowledge of where to train / quest. IMO: At least 10+ hours just to get to 30 for all classes
LOL, getting to 30 with orbis etc will take you 5 mins (this option is for funded newbs only who can afford it). Otherwise, if you just straight grind and find a good kpq party then getting to level 30 should only take you about 4-3ish hours.
Well, when ever you kill any enemy in orbis, they drop an item that has no use, and is stored in the etc section of your inventory. The beautiful part about this is, is that there is a man in orbis that will trade 8k exp, for 100 orbis etc. So, all you have to do is farm a lot of orbis etc. then trade it in for 8k exp and get to level 30 in a flash. after level 30 orbis etc is kinda useless, and getting Free Wins at CPQ is many times better at level 30. Hope this helps.
lol wtf you must be so slow at training. anyways.. 1-30 takes 3 hours if you grind solidly. 30-50 took me a day
i think after 50 the best spot is GS2 . Okay just went there with a cleric and a Bowman but both levled kinda fast.
I did it in a week just playing 3-5 hours a day (work + college). But of course, if you have the time to just grind it out in a day or two you can make it. Now that CPQ is back up those lvl 30-50 should be easy.
