I think that some new crew skills would be a good thing and the possibility of being allowed to have a fourth crew skill
would be helpful. I think that the crafting skills such as armstech ,armormech and cybertech need different sources of crafting material besides Scavenging or Slicing. For example , when I need a certain researched compound or metal if you have Armstech , Scavenging and Slicing for crew skills where do I get those researched items at?
