It is not a secondary prize if there's boxes with 1 or 2 crystals and nothing else. Happened to me six times at least. I really wanted to hit everyone on the Priority One interview this week, as the dev basically said what you said, and what the original event description said, but that just isn't what's really happening and no one points this out. If the point is to give people something, don't give them a box with 1 or 2 crystals, which amounts to effectively nothing. The blue consumables are better than that.

Hey I got this great idea why not use this new currency called latinum to buy speciality stuff!!! Oh wait yea you can gamble and get that already which allows you to get large amounts at one time.:p
