I felt it was the other way around. 2016 was simple and effective. Eternal just kept throwing shit at you, especially at higher difficulties. I kept hoping the big battles would end so I could move on, but more monsters kept coming. And then they threw the Marauders at you which just didn’t seem to fit in with the rest of the game because of how you have to fight them.
Sounds to me like you’re just looking to be irritated by something and you chose this.
