Personally i like the idea of respectively divided difficulty settings that was already mentioned here countless times in many different topics ...
So no simple "easy / normal / hard" ... but allow people to set all things they want like: "diceroll dificiulty in dialogues / enemy HP / enemy AC / enemy attack rolls / frequency of long rests / etc." ... simply let people set their adventure as they see fit.
And why am i talking about it here? Two reasons:
1) I would like to create
some encounters a bit harder for myself ... yet if all will be wrapped in usual "easy / normal / hard" settings it means that everything will be harder, and that option i dont like so much.
I wanted to de-trivialize some encounters, not make my charisma focused character unable to persuate anyone, since every diceroll dificulty just doubled, nor make some other encounters litteral nightmare.
2) Bcs in this case i would say that there is no need for RNG to "favorize small or big numbers", honestly im no programer so if there is a way i simply dont know about it, but as far as i know i cant even imagine how to implement such condition.
Maybe im wrong here, but i believe that, in this case its quite elegant solution to allow people to simply reduce (or incerase if they wish) default enemy AC in settings ... they will do it with some mod anyway, so why resist. :P
