Yes I do. Since we play a fairly hard sci-fi setting that resembles the Xenomorph setting (we actually used that to kick off the campaign) we pretty much always have humans as enemies; so essentially we make lightweight characters as NPC's. Though we do have some more elite enemies, they are usually still humans but in battlesuits or armor. It is an 8A setting, so no unrealistic SOAK 18 battle armors available - SOAK 10 is a top-of-the-line venutian battle armor (think The Expanse martian marine armor) and some ultra-heavy juggernaut-type armors have SOAK 12 or 13.You talk about buyable armor - so you design foe defenses like characters?
