I recommend this video to look more into OSR philosophy regarding the rules: https://www.youtube.com/live/bCxZ3TivVUM?si=aZ-y2U_AVjn9a6Ua
I think 5e is simple enough the issue is that its become ridiculously sprawling as WotC endlessly add more and more classes to the point that its eroding balance pretty badly.
Presumably you’re talking about subclasses? If so, I disagree to an extent- a lot of the subclasses have a valid reason to be included, since they fit more specific archetypes that people might want to play, for instance the conquest paladin fills a niche that doesn’t really have any strong alternatives. The issue I have is power creep- it feels like Strixhaven, for instance, throws the balance right out of whack with Silvery Barbs, while Tasha’s Cauldron gives us the Twilight Domain cleric with all it’s issues. If the new subclasses were balanced well, I’d be fine with having more of them, since players only need to remember the rules for the one they’re playing at the table, if that makes sense.
