If you a pretty big mmo player, and I mean like not new to them, you can reach lvl 24 on a cleric in like 2 and a half days. And in just a few more days 24 on a warrior. But, on a sorceress I still only have a lvl 10 lol, wasn't my style. Haven't tried archers yet, tho my best friend said you had to have really really great aim to hit monsters with them, so I don't know about them. So, I suggest warrior or cleric to start out with if you are new to Dragon Nest.
