I've noticed while pvping, something rather odd. I will burst someone point blank and do hardly any damage. The say it is due to the "toughness" and "Even Tougher" perk. So my question is, does toughness + even tougher take away damage for each bullet? Or from the entire burst? For example, say I bursted someone with a 10mm smg.
Normal damage would be
(8 to 15) dmg x 10 = 80 to 150 dmg per burst
with toughness + even tougher, would it be like this, (minuses dmg from each bullet) {(8-5) to (15-5)} x 10 = 30 to 100 dmg per burst
Or would it be like this, (minuses dmg from total dmg) (8 to 15) x 10 = (80-5) to (150-5) so 75 to 145 dmg per burst
Please no troll answers.
