I've felt that since oblivion, lvl'ed enemies were stupid, especially since you can lvl up purely from non combative skills. In morrowind it might have seemed boring to one shot everything past a certain point but there were still bosses, and honestly the best experience i've had to date was building an uber powered character without glitching or cheating in vanilla morrowind. The time and effort required, the feeling of power, becoming complacent and getting killed by the lich king in the mournhold sewers. Those were good times, but making every fight challenging for the sake of keeping the game exciting isn't making anything more exciting, it's just another time sink padding the hours, or worse, a source of anxiety because you've been lvling your roleplaying skills the last 10 levels by interacting with npcs.
