Except the point-buy vs. rolling discussion is germaine to all editions, not just 5e; and even though it's in a 5e-based forum doesn't mean all of us will automatically look at it from a 5e-only perspective. I sure don't.
And [MENTION=996]Tony Vargas[/MENTION] is right in one thing: the 3d6 bell curve, for all its flaws ( [MENTION=22779]Hussar[/MENTION] is spot on when he points out that 3d6 gives way too many extreme results to base a general population on) was the stated default for general population creation in 1e and, as it has not really been replaced or amended since, remains the default...well...by default.![]()
The forum is literally named "D&D 5th Edition News, Rules". There is no reference to using 3d6 for ability scores for NPCs in this edition, therefore it is no more germane to this edition than the rules for ability score generation in GURPS.
