So what is the current best way to make gil?

[Risvertasashi]

I am willing to invest into a crafting discipline if necessary, but at present I am irked that I can't buy the thavinarian gear that I think would look fantastic on me.

So what is the best way to make it / would leatherworking (or whatever makes thavinarian gear) be the better way to go?

Realistically, you'll need to level all disciplines for those nice cross class skills. It's more important on DoH than DoW/M a lot of the time.

If you just want to make gil... GSM has yet to fail me.
