I'm really seeing the necessity of sticking tot he triangles when crafting. I picked up artifact, treasure hunting and archaeology. Artifice is the crafting portion of my three skills, archaeology is the gathering/Mission combination and treasure hunting is the pure Mission portion.
What I discovered is that archaeology provides me with all the basics mats I need to craft a lot of the artifice items. If I want to craft any special items like yellow high quality lightsaber crystals, I need to collect those using treasure hunting. Without having the triangle skills I wouldn't be able to craft all the items I want. Plus, treasure hunting is providing me with the high demand items that people want.
I've also received a few purple quality Krayt Dragon pearls which will allow me to make epic level lightsaber crystals once I discover the pattern. You discover new patterns by reverse engineering items you've crafted.
So if you want to take crafting seriously, I highly recommend you to stick a triangle of skills.
