I used to say it as a joke, but why do we even have Fighters at this point if people don't want them able to participate in the oh-so-important 3 pillars (that we can't have rules for one of them anyway because trying to RP a character with social capability above your own is bad and wrong), don't want them doing anything in battle more than attack reliably or repeatably, and don't want them narratively capable of fighting high level monsters by being more badass and powerful than just like... a guy.
Joke?
IMHO, 5e with 7 classes, instead of 13 classes, 7 of which are superior to the others, wouldn't really be
better, but it would at least be more forthright.
Plus, the inferior classes, as mentioned above, could be retained as 3.5-style NPC Classes, that a player who was determined to, for RP reasons, and the party was ready to pull his weight/DM ready to adjust challenges accordingly could play if so desired.
Of course, if, say, Paladin were one of those classes and Fighter wasn't, it'd be nice to change the name to a the less obscure Knight, and include Oath of the Crown and Eldtritch Knight as sub-classes right in the PH. Oath of the Crown gives you a super-traditional, fantasy- fuedal, Knight In Shinning Armor, which should be as relatable as the benighted(pi) Fighter...
