I am way down on the list here but most of what is said I agree with I actually broke down and calculated my gain for my level 360 slicing. I sent my companion on a lock box mission spent approximately 1400 credits to send him on the (level 50) mission when the droid returned after 30 minutes he had 1700 credits in his lock-box if i am looking at it right then that means I made 300 credits. that's not worth sending a companion away for 30min- 1 hour.
It is possible that I mis-read the way it works but if not this is a major problem. As was said on the introduction post I am not saying we need to go back to spending 1200 credits and coming back with 3900 but some balance is in order.
