I think Archeology needs a buff to get it closer to Scavenging and Bionalisys. Not only bacause you can't farm kills to get mats, but because some are really scarce. Tattoine for example, it's a huge waste of time trying to get nodes. You're better off spamming missions over and over.
My suggestion would be that they should allow us to farm strong or tougher enemies who use lightsabers. I think this would put archaeology pretty close to what scavenging has with droids and bionalisys has with beasts.
