I agree, it just seems we just use that to ignore the most mundane of results. I'm saying take that a step further.
Put another way, unless there is significant risk of injury or a negative consequence, skills automatically succeed. When a roll does need to be made, it is only made because the challenge at hand is something a normal person cannot reasonably deal with, even if it's a DC 10.
Kinda like if you reduced the DC of all skills by 5, and then made anything that was "Easy" as now an automatic success. Essentially, you're just making skill proficiencies overpowered, although I sincerely doubt anyone can buff them to the point of being OP. Which is kinda the point.
We universally have this belief they're really limited, but there's virtually no benefit for them to be that way. Worst-case scenario, the Rogue or Bard with Expertise does things you normally would think someone twice their level would do, but...what's the harm in that? Does a Rogue being good at stealth make the game worse?
