In a sense, it makes you less risk averse, because there is no risk.
It’s not to get out of it by getting a Mulligan.
I’m not erasing all my roleplay choices with it, either.
But I killed the ox, so that’s on me.
Most of the time it is useless and gets me nothing.
But sometimes it’s important.
Scratch is my absolute best mate.
So in conclusion: savescumming is right and good.
