I figured I'd give it a try, and just as I expected I got Boss duration boost. The most worthless of boosts. A huge waste of the 9,000 kobans I had saved up. I want my Kobans back. I definitely agree with you that the rewards for the price are absolutely awful. I never give money to games that use Gacha or other loot boxes, and this game will certainly not be an exception to that rule.
