GM-only rules for creating NPC's in 5 minutes (or 5 seconds).
If someone posts a thread asking for ideas on how to reduce GM prep time, all sorts of good ideas come out. But by RAW, the designers seem to think all characters, creatures, npc's, etc. should use the same intricate character design rules. Wrong.
Let's have rules for designing PC's (lot's of options), and other rules for designing NPC's by role (mentor, resource, opponent, flavor) that only focus on the elements needed and, most of all, focus on quick design. Nothing stops a GM from designing an NPC using the same rules as the PC's, but let's have something easier for the other 90% of the NPC's.
