I enjoy scaling, feels like I can stay in a zone until the story is done and not have to slow down leveling.
I understand the “lost progression” argument, and maybe a compromise is that once you enter a zone mobs in said zone remembers when you entered the zone and will pause scaling until you out level the mobs by 3 levels, and then proceed to keep scaling to be within 3 levels of your current level (quests rewards will always scale to your current level).
