Devlin M. said: Because I can achieve the same amount if time saved in game by pre-rolling initiatives. Which is actually what I did when I had a climatic battle with 85 npcs. The normal D&D game isn't meant to simulate 85 NPCs in combat. At most, you should have 30 NPCs in any given combat. Anything more, and it's basically a war, which isn't within the scope of D&D at all. At that point, you should use some kind of mass combat rules at the very least. I'm not sure about D&D 5e, but older versions of D&D, like AD&D1e and 2e had BATTLESYSTEM rules. If you get the chance, you should check that out.
