I really don't get the whole "crafted gear is worthless because dungeon drops are better" perspective.

a) every single piece of crafted gear I place on the MB sells within two days, at at least 200% (sometimes stupidly higher) of the cost of the materials - that's anything from iLv 1-50. HQ mind, but if you aren't HQing your crafts you're doing it wrong (or mass-producing for desynth^).

b) I can understand why because ppl would rather use second-rate crafted gear whilst levelling so they can spiritbond it while they level and make a decent profit. If you think you need to use BiS dungeon drops from level 1-50, you probably need to address your playstyle before you worry about the injustice of the economy.

c) even post-50, players will rather use cheap crafted gear to spiritbond for materia either for gil or for their Novus when doing non-challenging activities like... well pretty much everything that's not in the last tier of the game.
