From here: Critical Rate Formula Discussion
Actual Crit Rate = N * (Crit Rate - Crit Resist)
Where N ~= .4
Str adds 1 damage AND 1 crit damage % while dex only adds crit rate, but also defenses .
For the multi hit skills with small base damages that archer has STR really scales well, compared to say barbarian who gets HUGE base damage on skills and can scale dex very well.
I’ve been going basically 1:1, favoring STR by about 10 points but I’m going to probably start moving to 2:1 soon or like… 4:3
