Since EXP and Gil rewards have been nerfed for HQ turn-ins from leves starting from 2.1, how are people utilizing their leves now?

I am now sitting on 100 leves again, after spending 2 days clearing out leftover stock to make enough Amber Chokers for about 10 leves or so. In terms of crafting classes, I currently have GSM/BSM/WVR/CRP at 50. While I have other classes to level, but at the moment I'm trying to raise money for FC housing using the classes I have.

I'd like to think that leves are viable gil fountains - maybe not so much in 2.1 compared to 2.0 - but I am struggling to find a way of utilizing them without spending too much time and money for the materials. For example, while I had a supply of Raw Amber and Electrum Ore, a single Amber Choker HQ costs me 21 Wind Shards, which at an average price of about 20g each, adds up to 420g per piece. Given that you'd want to turn in 9 Amber Chokers for the HQ repeatable leve in Saint Coinach's Find, a single leve costs roughly 3780 gil, while earning you 5.4k gil per turn in - this really isn't much in terms of money generated.

So, has anyone figured out the best leves to do per class, based on reward vs. cost? Or are battlecraft/fieldcraft leves the new way to go now? Just sucks seeing them sit at 100 leves, when I am earning slightly better money spiritbonding i49 accessories (they now have a rather small chance to give tier IV materia - a change added in 2.1).
