If you want to make gil "quickly" sell extreme primals wins. Get a group together that you practice with and fine tune to carry a single person. That or take your chances and try and play the market. Until new crafted items come in 2.2 there will be a dip in easy money making.

Also, you could try some leves. Some leves you can buy the turn in items you need (even if NQ) and turn in and make more gil than the total cost of the item.
