And yet the actions one type of Fighter would take would be consistently different from the type of actions another type of Fighter would take.
Being a particular type of <class> actually mattered for how you played and what you wanted to do. Being a particular type of <class> in 5e? Makes little to no difference. Pretty much all Fighters want the same kinds of feats. Pretty much all Warlocks want the same spells and invocations. Pretty much all Wizards will have the same staple spells, whether they're Diviners or War Wizards or Stupidly Overp--I mean Bladesingers. Etc., etc.
The allegedly huge variety evaporates rather quickly when you realize that (at least!) half the spells on your class's spell list aren't worth the cost of casting them.
You forgot to add an imho on that.
We're experienced players. Most casuals just want to have fun and use "bad" spells because they don't know any better.
Most players are casuals. I figured this out in 2002 when I discovered I sad the only one locally paying attention to internet discussions.
We are an extreme minority here.
It's also why 3E wasn't broken in most games because most people don't play like internet hyperbole claims. They didnt know how to break it or didn't have the required material.
Fireball hasn't been good (its B tier more average) since 2E I suspect it gets used more tgan every other spell at that tier. It's fun. Hypnotic pattern not so much.
