No, this is not another thread complaining about the economy of the game. Lol.
I'm actually just legitimately curious how you guys earn your gil, because I'd like to get underway saving up my own funds for endgame and beyond.

I would like to know which crafting or gathering classes have the best revenue tactics, and what those tactics may be. I don't mind spending some time doing this.
Which items are high in demand on the market? How do you play the market?

This is something that doesnt seem to have a lot of insight just yet as 2.0 is still young. But any insight you guys can provide me would be incredibly helpful.
