Myself im using Enchanting/Engineering as a shaman main. I love engineering too much to be able to give it up. And Enchanting stands well on its own legs, way too much stuff to DE to really need tailoring.
I used to be Alchemy/Engineering. But with the news of full-suite enchanting slots comming back, I dropped Alchemy. They will be able to craft flasks with extract duration, and Enchanting can produce cloak enchants that increases it further. Enchanting is going to in hot need to generate mats with the many more slots opening. And Alchemy is much less needed on a raiding main in SL.
