There is Health and Armor But what is Toughness? How is "Ranged" damage received affected by Toughness. Is Armor "softer" than Health? I feel when receiving ranged damage my "Armor" seems to go out way faster than my "Health" for the same amount.
@Whitefox550 can probably explain it better than I ever could. But basically toughness is damage mitigation. If your toughness is higher than the opponent's weapon penetration, you get a % reduced off the base damage you take when you are hit. If the penetration is higher than the toughness, you take the full amount of damage the weapon delivers each hit. Armor is basically a shield. it regenerates after a few seconds out of combat. Health only regenerates from less than 30% back up to about 30% and then stops. It can only be replenished completely by a healer, medkit, supply crate, rhino, or respawn. Hope this helps.
You know that it'd make everyone's lives easier if they simply renamed Toughness "Armor" and Armor as "Shielding."
Renaming "toughness" into "mitigation" would be a good solution. In simple words: toughness > armour in all directions. Lets say you have 100 toughness. Simple bolter can kill you with 10 bolts. If you add +30 toughness wargear, you have 130 and toughness and simple bolter needs 13 bolts to kill you. Its 30% increase. About armour: 1 bolt is 38 damage. So generally speaking when someone shots into you 1 bolt, it removes 38 of your armour. So if you add 30 armour, your survivability increases by 1 bolt. If you add 30 toughness, your survivability increases by 3 bolts. That is how I understand this, in the most simple way.
