Well I have level 15 mage and soon to be level 15 warrior

Problem is, Im having trouble of which one should be my main character

Im a mage type of guy, played RF/Ro/Rose online and i was a mage all the time

But in this game, it seems like its really wise and advisable to pick a warrior,coz they are the best in farming (since everything here runs on money) and they have the highest def, HP, plus their skills that saves you from using pots so much

So..I like a mage but keep popping pots....or warrior which is aright but will make you a Donald Trump of guy in the game?
