I'm intrigued. I cant see formulas on the spreadsheet, but clarifying question.
40% skill x 5 neutral element > 0%(?) skill x 5(?) strong element
Assuming that I filled in the blanks correct, how does it work out for this scenario:
__% skill x 5 neutral element > 20% skill x 4 strong element (This feels like what average players will aim for without rerolling)
If these two factors are multiplicative, I feel it should be something like (1.4)^(4/5)*(1.0)^(1/5)*1.2 = 57-ish%. It takes a similar amount of work to go from 40% to 60% in one element as it does to go from 0% to 20% in all elements.
