I just have to look at this message thread and see that many players if not all, have been playing this slot in hopes of getting something decent and we all agree on the same point. There is no benefit in opening boxes either before the patch or now.
Before at least you knew that by spending 2,000 credits you could earn 500-1000 credits more with much luck, that translates into 2,000 credits = 4 boxes.
500 credits = 1 box.
1000 credits = 2 boxes.
The benefit obtained was small but you had the possibility of investing money again, you could earn more or less but the system was more stable.
The system remains the same as in the beginning with the only alteration that now it will NEVER get benefits.
