Mearls: CR is BS, But lots of room for him to run

“Many DMs complain that CR is an unreliable yardstick for measuring an encounter’s difficulty, and ironically it looks like Mearls is among them. He’s now come up with a new point-based tool that’s apparently inspired by Warhammer 40k. The system assigns point values to different characters and monsters, and in a balanced encounter, the points will be the same on either side. It’s available on Github for free.”
