As a house rule, I'm wondering if having vehicle shields work like Reflect (on the planetary scale) might be a way to increase the staying power of ships.
This would mean that a ship with Defense 2 in a given arc would count as having Reflect 2 allowing it to reduce incoming damage by 4 in exchange for suffering 3 System Strain. Obviously ships with higher Defense get better deals on this (reducing more damage for the same SS cost) and ships with higher SST can make use of this more often.
Opinions?
