Thanks for looking into it. If I remember correctly Wendy has 2? passives that increase her dmg/crit and is the ranged squad with the highest dmg output.
As for Scuffy the problem might be the speed of her rifle? Since I cant see the values, I'm not sure why she can't 2x attack any enemies. Is it based only on weapon speed or agility or both? Since as I stated above her agility is really high
I guess it's fine if she doesn't deal too much dmg since shes half healer/half thief but needing 3 rounds for almost every normal difficulty enemy will just make her never see play in vanguard battles is my oppinion.
