I think fundamentally WOTC didn't use their surveys to provide the content that 5e fans would want. That's why there is this "real life human" conversation.
For example by Xanatar's, there should have been a fighter subclass that uses all the common origin tropes for a hero.
- Magic. You know magic: Eldritch Knight, Psi Knight, Echo Knight, Rune Knight
- Accident. Some event or series of events infused you with power. Werewolf Warrior, vampire Warrior, Shadow Soldier. Chaos Warrior
- Technology. You know how to craft magical gear. Arcane Archer. War Machine. Gunsmith
- Mutant. You are not normal for your race. Demigod. Paragon. Noble Bloodline
- Natural. You trained hard and have access to secret techniques which border impossibility or divert to another realm of skill. Warlord. Warblade, Swordmaster. Lord.
In the old days with the fast schedule, WOTC would have been forced to eventually provide these.
5e's slow schedule forced many ideas that require heavy playtesting to go into the Houserules sphere without the feedback and high recognition.
5e's book schedule is a bit too slow Especially with WOTC's light content in their releases.
