Have Heavy Weapons character which comes with Heavy Weapons Prof by default and also have Heavy Weapons Prof as one of their optional skills. Does this stack (give double bonus?) If not might be worth excluding it as an optional skill in the 2nd Tier if part of the default bonus of the original class
From what I understand class skill (one above) gives you proficiency with some type of weapons, so soldier won’t fail using them. Perk (one below) gives you +10% accuracy with type of weapon with which soldier is proficient. So they are complementary.
Thanks good to know
