I am not really interested in crafting so
I have come up with Slicing , Scavenging & investigation for gathering & selling the stuff on GTN so as to make credits.
Are there better gathering skills ?
forget crafting. It is a credit sink and you will spend an inordinate amount of time that will actually drain your wallet rather then enhance your equity. Bulk your toons up with scavenging, and bio for when you are in the field. Add in underworld metals and have your unused toons running those missions continuously. There is a huge profit margin. I can earn up to 300k in about an hour.
