I don't know about other players, but I've always preferred that much gil come from a variety of sources rather than just one major source; either farming or crafting. Since we're making XI comparisons...what I did was that I'd go camping several NM's several times a week with a few buddies and we'd sell/split the loot. That was a major source of income. When I couldn't do that, I'd hop on my craft, farm the necessary mats or buy them and then make a little gil that way. Later if I just wanted to get a little gil I'd go farming, but farming was probably the thing I did least since it's very monotonous to me to kill the same mob over and move again.

So yeah, I like combining different methods rather than just sticking with one.
