Cyberpunk 2077

That causes different issues.

It's cyberpunk. You're meant to have aim assist, hit confirmation, damage estimators etc. You're cybered, you're half machine, and losing your humanity to the machine to get those advantages is a core part of the setting aesthetic. Or alternatively, you don't get cyber, and you don't lose yourself to the machine, but then you struggle to survive when dealing with those who have. You see this play out in extremes in the cyberpsycho story arcs.

A cybered up merc is meant to be a small shark in an ocean of piranhas. An ocean where there are larger sharks, but also killer whales. A cybered up merc is meant to be a threat to most people on the street. But a gang of partly and non cybered folk should be a threat to the merc too. Maybe a merc could get lucky and tear up a gang by themself, but it would leave a power vacuum, and disturb a lot of people who had deals with that gang. It would be a story in and of itself. And any merc that kept killing wiping out entire gangs would eventually take a wrong step, and end up dead, or if they were good enough to not get killed by the gangs, they'd find themselves with a bullet in the back of the head, being put down by the corps who rely on the status quo in the streets to make their money.

The point being, the cyberpunk setting itself is not designed to be home to mass slice and dice combat. The slicers and dicers are the people who have lost themselves to the machine completely, the psychos that need to be put down.

tl;dr - Changing the difficulty wouldn't resolve my main issue with the game
