A simple one, add a tailoring shop. Tailoring in this game is severely lacking. All other crafting based skills get both a shop and an outfit to boost them.
Herbalism all get both.
Tailoring gets nothing. Which is why you never really see many people with padded or leather armour, when you can use those leathers to make top quality metal armours that are dirt cheap, and provide alot more protection. The only reason to get tailoring really is for the outfits and backpacks. To help reduce the ease of making metal armours they need to be alot more expensive, something like 3-5 bars/ingots for 1 piece. get rid of copper and make it iron or even steel for the higher tier armours. It gets old really fast seeing everyone running around in plate armour.
