what pairs well with Scavenging as a trooper. I have aric going to get scavenge stuff for me but I am not sure what to do with all of this.

I wonder if it's better to sell the materials or should I pick up a specific profession?

I read most people aren't buying gear right now because the game is still new and everyone is learning.

should I choose a profession like armstech to benefit me, or can I make money getting another skill?

I have 2 crew skills empty.

Cybertech, Slicing.

Build green crap with Cybertech out of the Scavenging Crap. Sell to vendor.

Send your companions on slicing missions for $$. Loot lockboxes throughout the galaxy with slicing.

Or pick up bioanalysis and slicing. Those 3 are money makers together for someone who prefers not to craft.

Bioanalysis subcombines sell very well. People are offering them for sale for about 5 times what they cost to get through missioning, and there still isn't enough available. You can also crunch down hard beasts for bio stuff the same as you do for breaking down droids.

That way you are making money no matter what type of mobs you end up fighting.
