An Army of Many

One side benefit of the flat math of 5th Edition D&D is than an army is actually a threat. Previously, the continually increasing math meant a small army of low level conscripts was about as useful against a party or high level adventures as swords made of damp cardboard. The king ends up with little authority over a party of murder hobos as even the threat of a few batallions of soldiers doesn’t phase them. This changes when the odds of a soldier hitting increases from one-in-twenty to one-in-ten while the adventurers might also miss twice as often. The army is suddenly a threat.
