Huh? I'm not trolling, I'm deadly serious.


From what we've seen in the Basic rules, 5E doesn't have a skill system at all. It has a binary proficiency system which heavily relies on ability scores and provides an automatic improvement of all proficient skills as the character levels up.
An ACTUAL skill system would allow for far greater granularity, rely more on actual skills and less on ability scores (the emphasis on ability scores has been a major annoyance of mine in Next/5E ever since the first playtest package came out), and have a greater number of well-defined skills rather than a dozen incredibly broad ones.
It is entirely possible that the DMG will contain such a system. I hope it does.
That's fair. I know some people swear by Hackmaster, and I'd love it too, if it weren't for the freakin' detailed skill list. That drives me batty.
But different strokes and all that.
