I've been saying this for a while now, but I figure I'll say it now before we get our next promo and it already has the frameworks set up.
It would be wonderful if we could have a large difference between purchasable prize boxes, and bundled bonus prize boxes. Standard recolors for promotions are great as standalone boxes. However, boxes that have a high chance to not give you your money's worth ($5 =/= 20k crowns) are a bad practice.
Thus, I suggest that the two promos that follow this pattern (Equinox and Solstice promotions) should use the "old" method of promotions, bundling a box with every $10 of energy purchased. This means that you are buying energy, and getting a small bonus. You don't lose anything from the boxes.
All recolor boxes are worth the $5 simply because no individual accessory or costume has a price tag already put onto it. UV tickets do. Players might not value a sapphire headband at $5, but Three Rings values everything in a box promo at $5. Similarly, Three Rings values a 20k crown UV ticket at 20K crowns, and when a UV ticket fluctuates in price between 200-400 energy, the $5 (1,600 energy) price tag on that is going against their own values. As a bonus box alongside energy purchases, the boxes are no longer binded by pre-determined prices.
Short version : Make boxes with high chances at UV tickets (or anything with a pre-determined price set by Three Rings) be bundled with energy. Have boxes with new cosmetic-only items inside remain as standalone boxes.
As someone who hasn't payed money on the game since they got rid of Box+Energy promos, I'm just gonna say +infinity. It would be nice to actually be able to support the game I love but with no incentive why even bother. I'd just like to know I'm getting my money's worth, but of course, I'm just one person.
