To be fair, 2014 and 2024 d&d both have a ton of mechanics that are meta. They have non-magical influence over PCs like 2024 lion roar applying fear. Or like inspiring leader always meaning whatever the other players has their character do or say you end up inspired by them, every short and long rest. They have tons of limited use abilities that aren’t easy to dietetically explain in full. Ki, Battlemaster manuevers, 2nd wind, rage. Heck, even sneak attack being rogue only, as in why can’t my fighter sneak attack while the Barbarian is next to the enemy is meta just without the decision point.
I think we often overlook just how much of this kind of stuff modern d&d has in it.
