I does not know, if anyone agree with me, but I think, that it will be more realistic, if gunshots will ignore some of armor, like 25-30% , so guns will not need high stats to deal lots of damage. Based on basic attacks for Ryen, Tsubaki, Mirel, Sandra and Elly, where Ryen do about 900 damege + crit, Mirel about 700 + high crit chance, Tsubaki and Sandra about 600 and Elly  around 350. Ryen have equipped katryx blade and blade from old adventurer, Tsubaki have setsuna, Mirel repaired old bow, Sandra two black daggers and Elly steam gun.
