There are lots of arguments around level scaling; I think on the whole I dislike it, but primarily for aesthetic reasons. It isn't so much about what the game does, but about how it feels to be in some of these situations. There was a relatively famous run - for Alliance players, at least - through a writhing zoo of Level Fuck You crocolisks to get to some seaside fort with a Gryph point. You had to unlock it for each character, and so it was sort of a rite of passage around… level twenty, maybe? It's been a minute. All I remember is the terror.
