I think you just look around fiesta scene, you are saying that we should remove item mall because you are trying to have a point on f2p vs p2p, nobody does that because item that make your char stronger needs to be "regulate" if not > OP server.
Class money making, you tell the lack of spots, well OLT, 100abyss, black bear, subjects, LN, dungeons, phouch, and i may forgot other, those mobs drop greens and weap galore, or rare stuff that can be easily sell. About the class all is about how fiesta is made, it's like leveling difference between classes.
