I like that NieR Automata has a secret difficulty setting to adjust that the game doesn't really tell you is a difficulty setting. And that's the companion aggressiveness thing. I like playing without the helper character because it means I have to 1. Learn more about enemy combos and behavior and 2. Feel like normal difficulty is more difficult without massively changing an aspect of the game like the jump from normal to hard.
Also just as a side note: man, I really appreciate the opening moments of the boss fight in the desert city on the second playthrough, hits really hard.
