If crafting can allow me to customize my gear, so make a +1 set of studded armor look different as an example. YES. Yes I need crafting to be in the game.
If it allows me to boost items I have and like the look of, say make a +1 Scimitar a +2 Scimitar of acid - YES. Yes I need crafting in the game.
If it is just another time and inventory sink in order to make healing pots, I can most likely get by without it.
