I'm not really up on the crafting and gathering game, but I grind out all my gil doing dungeons, hunts, stuff like that. It can take a while to earn and don't think I've ever had more than the 400,000 gil range. Most of my world's market board gets unbelievably expensive and it can be near impossible to get stuff.

I was just able to get a glamour I've really wanted using the world transfer system. Still had to grind for it, but I got it. My home world originally had a way pricier one and then that got snapped up before I could get near it.

Idk if this offers any perspective, but for me at least the world visit system has been a relief. I wouldn't necessarily feel the need to world hop scouring for the lowest price if I had millions of gil and this was just a drop in the bucket so to speak. It's just if there's something very specific I'm looking for and struggling to afford.
