When your ship's shield soaks up damage from hits passing through, will the shield power drain and have a recharge mechanic? If so, will shields at lower power or integrity provide diminishing returns?asked by XenoChef

Yes. Shields do recharge over time, some faster than others, and as the shields get lower powered, as they take damage, they actually do stop fewer things from going through.

So more things will pierce them, which we call what, Ben?

Pierceability, I believe.
