This is a spin off thread from one of the long and meandering "Monsters of the Multiverse" threads.
The question is relatively straight forward: do you prefer that NPCs and monsters operate by the same rules as PCs, or that they operate by their own rules. One of the most basic ways in which this might appear is should NPC and monster spellcasters have to use the same spells available to PCs, and if they don't that means the PCs should be able to learn that spell. It extends to racial abilities: if a monster race has an ability, does that require that a PC of that monster race should have that ability as well.
3E was very much in the camp of monsters and NPCs being built by the same system as PCs. This led to what i think was an interminable process of building NPCs and advancing monsters, which resulted in only marginal benefits (if any) in the actual play of those monsters and NPCs in a fight with the PCs. Older editions did not try to conflate them except that some monsters had "spell like abilities" and leaders were often indicated as "fighting as an x level y". 4E had monsters operating under theie own rules -- and just for full disclosure, while I was not a fan of 4E I do think the 4E monster stat block was the one thing the edition did right. 5E seems to be treading the line between the approaches and is probably closest to the pre-3E model in most cases (although the stat block is bigger).
I am in the camp that monsters do not need to use the same rules as PCs and in fact shouldn't. Players should not be able to look up what a monster or NPC can do in the PHB. Spellcasting monsters and NPCs should have their own list of magical abilities, all accessible in the statblock. Same for "feats" or "class abilities" for NPCs and monsters.
What is your preference?
