Smuggler Archive

When i find a lock box in a bunker and it said it is lock, when i try to use the slice command it tells me i cant open it. Why is this. I thought a smuggler was able to try to unlock locked items. " im not talking about locked contaners loot items" bit the loot boxs that are on the ground in the caves or bunker. Right now i dont see much use for a smuggler other than selling faction points and slicing gear. So my questions are

1. Why cant i open the locked contaners inside of bunkers and cave's

2. Why are there so little skills for a smuggler i know they have low blow and ect but they should have a better weapon to use for the class.

3. Is it realy worth the time to get a master smuggler.
