Bunkers! Everybody needs bunkers! When you have a whole bunch of armor platforms on the surface, your valuable people can survive combat. With the changes to armor & defenses, it is likely that a few ships will manage to limp past your lines and fire some potshots. Get your people underground, and save lives
Just remove most of the weapons from the platform options. Missiles might be OK to leave in (shorter range maybe?), some range-1 PD would be reasonable too.
