I'm not sure if i'm the only one, but i don't get why, and i hate the fact that usable items drop from treasure boxes. Especially on end treasure vault levels like after danger missions. It makes no sense why i would want a barrier/vial/capsule when i can't use them. And i don't want them to take away from treasure either. I don't want them in treasure boxes, i barely want them on kills. If there is another thread i'm sorry. This makes no sense though, and should really be fixed. It makes no sense to be in treasure boxes at all.
