Point-Defense on fighters?

[Fyron]

Seekers are not all or nothing. You can kill them with 2+ hits of weaker PDC.

But to maintain the same seeker kill rates, you can just lower their damage resistance by the same ratio you lower the PDC damage. This will weaken the PDC againts units, but have no affect whatsoever against seekers.

Ah, my mistake then, I always thought it was all or nothing.

[Suicide Junkie]

The missile either does full damage when it hits, or is shot down.
But any damage taken by the missile adds up until the missile dies.
