[Strategia_In_Ultima]

Make multiple types of PD!

Make small, rapidfiring guns that can target only seekers and have a big positive weapon modifier (as the guns fire very rapidly, you can easily predict the path of your bullets). Make PD missiles, in various sizes, with smaller, more rapid-firing versions targeting all but doing minor damage, larger ones target only fighters/sats/drones and doing larger damage. PD lasers (as in Proportions (or was it P&N? I get them confused all the time.)) that have a large weapon modifier but fire slowly/do less damage/are very large/etc. Very large PD cannons, that have varying ROFs (lvl 1 has ROF 4, lvl II 3, lvl III 2, lvl IV 1 etc.) and do large amounts of damage and have the capability to target all small things but which are prohibitively large and expensive (think 100kT, 5000 minerals).

Experiment a while and think about what you prefer.
