Yep. Barbarians since the ancient Romans was never a glamorous therm.
But in a RPG context, people hear barbarian and expect to see “Conan”
1 - Be a antiquated concept doesn’t means that is bad
2 - There are a lot of classic RPG’s without classes. Arcanum for eg, you don’t choose a class. On Gothic, you also doesn’t choose a class. You start in the bottom of the food chain and needs to find someone capable and willing to teach you to learn anything. Your animations and stances changes once you become trained on one/two handed fighting and it is amazing. Never saw it in any other game.
And to learn magic for example, Corristo only teaches you on mid of chapter 2 if you joined his camp and answered his questionnaire rightfully . You can join the Fire/Water mages or the Sect camp and if you don’t talk to a master to teach you magical circles, you will never learn magic. You “class” is more like your “title” on Gothic 1/2/3.
Dark/Demon Souls classes affect the starting equipment and starting stats. But you can pick royalty and never use soul arrow.
Games without classes can work but IDK if Diablo could work without classes.
RPG codex is the biggest RPG forum in the world, almost everyone liked the implementation of D2’s necro. Except a guy who argued that be able to raise skeletons from a swarm of insects corpse makes no sense.

Yep. When every monster felt like just different health and damage bars, the games becomes very monotonous.
