Well there are already a few that just need outright fixed (Fausts speed), but I was thinking about this when my VPS got crafted with a Normal Defense High UV. Why not make the bar start to overlap from the beginning of it in a different color to indicate that it's got more than what it actually shows because of size restraints in the game? That way you wouldn't need to change the whole system trying to fit everything into one bar.

And this would also help people discern the exact differences between equipment with seemingly identical stats but do not act as such (Ancient Plate Shield and Volcanic Plate Shield)

I'm no coder, but this wouldn't seem too bad to implement. And I'm sure a lot, if not all, players would love to see this addition.
