Why patch the behavior of level scaled quest rewards such that they change attributes to match your level as you level? That way you can enjoy the gear at lower levels but still benefit from them at higher levels and therefore want to keep them?

NO, they had this in Oblivion and it was horrible. Its much better when everything doesnt level scale.

They already scale like Oblivion. What I'm saying is that for the armor that you've already gotten, it should be able to change stats according to your current level as you level up. That's only for these quest rewards, of course. Otherwise I find myself wondering if I should wait until higher levels to do some of these quests and that's a bit silly.

If someone doesn't like that option, they are always free not to use the armor.....

Yeah, I would like that. This way the nice pieces stay valid throughout the game. On the other hand, that brings new problems: You could get a quest reward at a level where the quest is easy and still have the benefit as if you did it on lvl whatsoever....
