Edit: I think Larian should list the number on the d20 you need to roll, not the percentage chance of hitting. For this exact reason: it feels more unfair when you miss with 95%, than you miss on "Need to roll a 5 with advantage"
I can support this idea. It's already existing code in the game (Social DCs). So for combat it'd be AC - proficiency - modifier. For spell save DC, show the characters spell save DC in the UI.
