Feels like it if they want to simultaneously have fighters that are:
(1) close to real-world-mundane,
and (2) balanced in capability with the other classes,
and also (3) have Wizards who reliably do all that 5e Wizards do including during combat
and (4) have the game involve physically fighting huge monsters that would crush anything close to real-world-mundane
... because those seem contradictory?
Simply substituting "real-world mundane" for "in game world mundane" feels like it makes it approachable, as would giving up the balance, or nerfing wizards.
