So what is the current best way to make gil?

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.

There is also the gathering classes like Miner and Botanist since mats are in very high demand now with 3.0 still being young.

Also using the retainers to gather the right mats can give you a good amount of gil each day by selling those mats to other players.
