There was no scaling in Morrowind.
That is true. There is very little in Oblivion, for creatures/undead/Daedra, anyway, while we're on that subject. Most of it, in both Morrowind and Oblivion, are difference creatures spawning based on the PC's level.
Anyway, I would prefer to have the situation handled more as in Morrowind, especially if we're discussing item scaling in this. I hate unique items being permanently stuck in a weaker form due to obtaining them at a certain level.
