Standard mission loot chests

Wondering what the point is or how its calculated. For instance, I just played a level and after beating the boss got 15 chests. Victory celebration only gave me 3 1* items. So what is the point? Shouldn’t I have gotten 15 items or items in rarities that add up to 15 (Like 5 3* items)?
