I don't know why you're stating the obvious. Of course improving the economy is going to improve the game.
Anyway you just don't appear to get it. My post was about preventing the massive deflation that is occurring for crafted items while preventing massive inflation of the super rare items. Super rare items being the equivalent of a Kraken club in XI. Gil is a problem, if five billionaires want an item and only one of them exists you can expect to pay hundreds of millions for it. Did you not learn anything from XI's economy in 2005? You're making the assumption that nothing in this game will be as rare as that.
Your post doesn't make sense. I am one of these crafters you talk about, yet it's my idea to fix the economy in this way. I think most crafters who make a lot of gil would agree that items need more value and there's too much gil in the economy.
You got goldsmithing to 50 (kinda funny how similar our classes are haha), are you happy with your jewellery being worth 10-20k a piece? Or would you rather the gems be rare so that you could sell rings for 200k each? Does a high end ring that costs about 10k to make being worth 15k sound like a healthy economy to you?
Surely you can see the economy is broke. I might not have the best ideas for fixing it but some big changes need to be made and I can't see any flaws in what I propose.
