Honestly bro, sounds like your own problem. I'm up to 300k and I'm not even max level yet; I've gotten that just by playing the market board alone, nothing to do with crafting or any thing.

In the mean time, I've also been steadily gaining levels on my main, and have had enough time to dedicate levels to other jobs as well.

How exactly is it that you ever planned on getting Gil in the first place if you never had any intentions on working towards it?
