Here is 2 ideas for Unwanted Lock Boxes.
On ground or in space,Lock boxes would make excellent target practice. See how many of them we can blow up.
That Lock boxes be used as another form of Torpedo ammo to fire at borg ships or cubes.
I am not prepared to spend real money on lock box keys,if all we get is rubbish prizes from these boxes 99% of the time.
Change the prizes to something substantially better,to make it worthwhile buying the box keys.
The current prizes are total crap and rubbish.Result is less box keys sold.
Better prizes guaranteed,more box keys sold.
Just put the stuff in the c-store. Prices there are already hideous, and folks can actually buy what they want instead of trying their luck in the lockbox lottery, getting pissed off and refusing to ever deal with any of cryptic's subsequent money grabs.
