Thanks, I'm playing with my nephew and went Trooper instead.
armormech, scavenging and slicing.
yo dont need underworld trading as your cybertech should already have it. scavenging is good to get level appropriate mats for yourself and companions. slicing is for augment materials, schematics and augment kit materials.
you will be able to make all of you companions gear except the droid which your cybertech can do. also at 50 you can make augment kits and aim augments saving lots of credits or even make some.
one of the companions has a +5 crit for armormech too.
