There is such thing already, where you can exactly get those kind of informations. When you go for an expedition, you add 4 modifiers and begin serasiel or whatever it is called, on the end of map, you don't have second map, you just have portal to city, but when you turn back completed exp you are graded and have info how you perform, how much dmg, biggest hit, how many enemies you defeated etc.

Thats exacly what i said.
Imagine that whenever you wish to modify your build just a bit, you have to go thru the whole run to see the the results. Thats tiring.

quite so
