Crafted sets has one benefit, sharpened weapons.
You will normally use shorter time level up weapon crafting to 6 traits than getting sharpened weapons of the type you want,
this is typically fire and shock staff or two daggers or two hander and bow, and research work wile logged out
But you can pay an guildmate to craft it for you, 10K is pretty standard 20K if generous or have an more complex order.
If you are an noob you will get it for free from most.
