That’s what they mean though. Weakspots multiply the damage received. Their only lever without redesigning the way weakspots function is to drop base damage.

The Arc Thrower for example ignores armor but does relatively low damage, however sometimes it will oneshot a beefier enemy when the arc hits a weakspot. Even with the flamethrower it is better to hit the charger’s armored leg because that is a weakspot on that enemy.
