Actually you're way off base.
That is not how it works. I suppose if you don't pay attention if could appear that way. As in Morrowind areas don't respawn like they do in ES IV and V. When you enter an area in Morrowind it spawns enemies based on your level.
This is how it works in all ES games, even Morrowind. If that wasn't true Cliffracers wouldn't present any threat once you reached higher levels. But they do throughout the entire f-ing game.
The FO system is not how it works in Skyrim. I've never encountered an area in Skyrim that's effectively off limits like Old Olney in FO3 (I only just got New Vegas last night).
That things you're complaining about in Oblivion have happened to me in Morrowind.
