Most of my save scumming comes from being annoyed at the random factor. Like I have a +8 on Skill and it rolled me a 3, failing? Nah that's stupid. Reload.
Less random, less save scumming. You can have good systems with low random factors.
Inspiration helped in bg3, but it's a pretty limited resource and can still fail.
I did save scum once in a fight where I rolled four natural 1s in a row. The odds of that are too low for me to believe that was legitimately random.
