Crafting. Some cheap, some expensive.
Crafting is tough. Especially when doing it head on legit staring at the pc and just spamming the button for the command. I use a 360 turbo button for the pc, but it hurts the craft materials being lost without using the abilities like maker's muse and what not for safety. Thing is, I'm talking about the differences for various craft jobs. Personally, I find that weaver, carpenter, to be the cheapest. Leather worker happens to be the most expensive. I know I can farm them but it's becoming competitive and other alternatives to find the items needed are bazaar'd at 999,999,999 purposely on the markets.
Even worse, whenever low items are available they are all bought and listed to 5x the price in the bazaar. Yes, I can use the advantage of using the market when prices fly up, but there's always going to be an underdog going to low price me to control the economy.
