You are missing the point. I agree that the fighter is scared both ways.The fighter is still scared if his save is 5+ points lower than the rogue's over the course of his career, though.
Again, I don't get how you need the wonky scaling, "bounded accuracy" should ensure that the difference in ability scores take care of the fighter's lower chance to dodge a fireball ( or what have you ).
You are turning words around now, and losing some continuity. But to try to repeat: you said " ""Low chance of success" is one thing, "bad scaling" or "no scaling at all" is another thing entirely."
In context you were allowing that low chance of success is ok (and you further reinforced this point by stating that DC should just be made high).
I am stating that within a bounded DC system "no scaling at all" is NOT "another thing entirely" from low chance of success.
On the other hand, if your only solution is to keep saves close together but make something scary by making DCs really high, then you are forcing it to be scary to the rogue also. It might be a little less scary to the rogue. But to the extent that you require the saves to be close together you also require the scariness to be close together.
