It's what i hate of this feature. People show their greed and their uncaring. I've experienced too many times battles with a certain outcome where the enemy stopped my mysteries even if i had just one single ninja left and the mystery landing would have killed 1-2 enemy ninjas at most after which even on autoattacks i would have died. It's pretty stu(pid) as much as is the fact that if you win two battles and you kill 16 ninjas, after you claim the reward for 10 kills the other 6 don't automatically get added to the following counter, imposing on us to win at least one more battle than necessary, as much as makes no sense that I'm kage and i get chunin or jonin boxes. Wtf.
