My woodworking is 70, my highest craft and it's pretty recent. I'm glad it was cheap to level because it hasn't made me much gil.
Here's some things I'd love to see for crafting.
Linkshell shops. I can craft shihei and bolts at a profit, but it's not a very big profit and typically if the crafters that consistently make shihei see someone trying to hedge in, they'll collectively undercut to push you back out. Nearly everyone uses shihei and enough people use arrows and bolts that I'd love to see an LS shop or mini-AH where only people with my ls's pearl could buy. This could also benefit the resale of unused gear, you can sell to friends at a better price for them. This would also free up some of the AH activity and cause prices on consumables to rise to the point of being worthwhile again, perhaps.
Wotg-supplies crafting.. We're at war! Those npc's use bolts, arrows, shihei, it would be nice if we could be given, or use AN points for parallel 'special' ingredients where we could make like Kingdom Shihei, Republican Shihei, Federation Arrows, etc that could be traded only to npcs for a gil reward.
Just some ideas~.
