A little new, I guess.I'm sure there's varying degrees of emphasis placed on other ability scores at various tables at any given e, but 5e seems to emphasize a breadth in ability scores that is a little new for D&D.
Obviously, classic D&D never emphasized breadth of ability scores, with it's random rolls and bonuses only for quite high stats. In 3e was a severe disability, if not a terminal illness for a character class, but you still wanted DEX (das uberstat), CON (hps, FORT), WIS (will, spot/listen) and INT (skill points) in as much as you could manage it. 4e's handling of non-AC defenses gave you more flexibility in which stats you emphasized, and gave you good reason to try to keep 3 of them up, but only let you bump two stats at a time, so it never quite worked out. Even so, you /could/ get by with a 16 to start in a prime stat (even if you didn't have a racial bonus to add to it), thanks to all the 'math fix' furor.

...
In 5e a high stat is more critical than ever, since your stat, at up to +5 is going to be responsible for most of your bonus prettymuch your whole career. It's just easier to max out a stat earlier or later in the game - and, if feats are available, there's a tradeoff. You do, though, need three high stats for saves: CON, DEX, and WIS (just like 3e). And, even if you cover them, and are lucky enough to have one of them be your prime stat, as well, the other three can still pop up and bite you.
Likewise, you never know what kind of non-proficient non-prime/non-save stat check your DM may decide your character's life depends upon...
So, yeah, in a sense, everyone's MAD in 5e.
