With all the hatred and vitriol surrounding the cardassian lockbox i have a few suggestions for next time.
1) sell a reusable key for 5,000 cpoints that is specific to that lockbox. The key would have a 20 hour cooldown. What this does is it gives people a choice, pay 3 times the cost of a normal ship upfront and be assured to get it, or roll the dice with the master keys.
2) reduce the drop rate of the boxes (cut the drop rate in half). This will encourage people to buy more keys since the boxes are more rare it gives the illusion that the drop rates should be higher.
3) make the ship (or whatever super rare item) be bind on pickup. This would serve to counter a group of players from pooling resources to stockpile boxes and have the 1 person with a reusable key open all of them.
4) dont tell us who got something from the box. It leads to harassment from players who are protesting the grab bags. If you must advertise how many ships have been claimed do so in the chatbox and dont name anyone. "The 10,348th galor has been claimed! Try your luck" would be acceptable.
