The problem is with your perspective. I know it may be what you want from the box (and it is probably engineered that way to drive sales) but the crystals are really a secondary or "extra" prize. Since its introduction is new there is a shortage of these crystals. Eventually they will accumulate and it wont be AS MUCH of an issue.
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.
