I cant believe anyone farming solo killing mobs 1 by 1,yes all have tried that but most efficient farm from 20-40 is aoe ac/for.I always want a spoiler in my party,to get extra mats.For the newbie weapon,if you non stop farm 7days you will reach 40lvl,but we must not have real life for that time .Archer is harder to exp cause noone wants them to aoe party cause of no aoe skills,you must create cp too boost archer.Crafter i think is the best money making class and after spoiler,no need for you to reroll,you can farm your items(mats) but you cant craft them,no big deal.Every class is playable and fun but i believe with a cp its more easy,but hard to create one.
