id say that cleric is the easyest to lvl in solo beacuase they can single monsters only using sp while fighters mages and archers need hp/sp. also i think that cleric are the best class or atleast the most importaint. also cleric are the easiest to ebat the lvl 20 and 60 job change quests. it took me 4 tries on my fighter for the lvl 20 and on my cleric--first time
my paladin on lvl 60 quest--first time my *almost* warrior --still trying to beat it
now i would say mages are the hardest to lvl up.... mabey its beacuase the lac of phisical defence...i reald dont know (my mage only lvl 13 *Black_Magic8520*)
archers hmmmm again i dont know too my my archer only lvl 27... but im not saying they are imposible---but--ugh--just here in my lvling easyeiness list
1.Cleric
2.Fighter
3.Archer
4.Mage there....
