Here's a hint to the concept of role-playing in the context of Role Playing Games: if the identity of the character you are playing is that they are physically adept, this should remain so even if the player has the dexterity of a paraplegic, can't press buttons in time, etc. Likewise, let's say a character is established as being profoundly physically inept, no amount of player ability in action games, no amount of dexterity with controller or keyboard should make the character physically adept. So all this talk of skillful mechanics, being able to do low level runs, roll timing etc has nothing to do with the genre and I'd say is even antithetical to it from a purist perspective. Even another Action-RPG, Diablo 2, got some of this right, like the character auto-blocking depending on THEIR dexterity, not the player's. Now, since video games are unable to fully simulate a true RPG experience, we allow for these things to exist on a scale, so one can correctly say like Diablo is a kind of RPG, and Dark Souls is some kind of RPGish thing, but they are far less RPG than Fallout 1. This is why we have subcategories, duh.
About low level runs in RPGs: In PnP games -which without the genre wouldn't exist in computerized form for wrong headed developers to bastardize - levels were meant to represent your character's ability/job experience, within the power scale of the game world. So a level 1 being is not supposed to have much of, if any chance in a head to head encounter with a level 10 being, especially with no party to support them, as is the case in many of today's video games. If you can circumvent this through "player skill", then you are then not role-playing a character at the bottom of the power scale and then levels become a difficulty slider instead of fulfilling their intended purpose as dictated by the foundational works of the genre.
Sorry, you cannot take tabletop out of the equation. If a video game is in defiance of core tabletop values, the fucking foundational values of the entire genre that video game developers are pillag-...sorry I mean emulating, then it is less and less of RPG. I'd go so far as to say video game developers don't have the creative authority to take something they're merely borrowing and change it to suit their whims and have it still be legitimately regarded as that thing.
