Think of Aragorn, for instance, a master survivalist, one in a generation. That can't be implemented with 5E. The old 1-20 system was a bit crazy, no system needs that many different degrees of expertise on a skill, but replacing it with binary may be a net loss.
This is a decent example, and I think the main thing would be to adjust how you think of skills. Someone like Aragorn might be a range with an unusually high wisdom score (18-20 range?). This seems consistent with the character in the books.
In WEG D6, skills are based primarily on attributes. You could become quite highly skilled even lacking a high attribute, but it was harder... making the system a bit strange in some ways since related skills were often beneath a single attribute. I feel that 5E is mildly similar in this regard and gets back to more of a 2E feel as far as skills/proficiencies are concerned. As you may recall, back then, proficiencies were based on attributes and were a binary Yes/No proposition.
On a different note: I've been finding some of the rules in 5E a bit haphazardly organized... like classes have favoured saving throws. I had no idea what those meant at first, but reading some other sources, it seems to be that they get their proficiency bonus added to them? Also, there is no more skill for opening locks or disarming traps now? As far as I could tell, it's based on perception checks for spotting things and dexterity checks for picking/disarming. Is that right? -- I've been meaning to take a closer reading of the rules, but I simply haven't had the time lately.
