im currently slicing, scavenging, and investigation.. alot of ppl say slicing isnt profitable but im sitting on 500k credit surplus at lvl 40 after getting t2 speeder
thats also never doing space missions/heroics, sending 2 companions on rich gift missions every chance i get, and not selling anything other than augs/discoveries and schematics from slicing
while 500k isnt a large amount, ive been pretty reckless and dont do anything other than slicing to fund my habits
drop armstech and just pick up slicing till 50, itll give u plenty of credits for leveling and u can just drop it later
