Starting out is slow until your second companion. But I have artifice, biochem, and synth. All of these have given awesome rewards once I get really into it. Each one fits its respective character well and I help my other alts with each skill. And even though reusable medpacks are now biochem restricted I can still sell my blue ones. All in all, I'm beginning to enjoy crafting much much more.
P.s. those who put up 99 amounts of items in the GTN your life savers
