Gil is really only needed for glamour items, really. Unfortunately if that’s your thing, MB sellers tend to be greedy and sell very expensive. The only way to make any real Gil is through the MB. Big Gil drops don’t happen outside of MB. Tens of thousands of Gil is what you’ll get, not millions. I personally find crafting and gathering to be very boring, so I don’t spend my time doing that. I’d rather be adventuring. I just wish you could make big Gil doing it as I do like glamour items which are too pricey.
