Since you get 3 free temporary points in crafting pretty early into the game (trait+bracers+belt, if you count the one given by Scientist, it's 4 'free' points), is there any point in spending 15 SP on crafting? Do you get any bonus or are there high level stuff that require a crafting or blacksmith of 6 or higher?
I understand there's a built-in respec function but I'd rather plan things ahead, because respec is in itself a major PITA.
