Except that it's totally possible to kill dragon priests very early in the game, with the right strategy. And even the masks, while unique, are still a bit underwhelming if you've leveled Enchanting.
There should be some loot, somewhere, that is better than anything you can craft for yourself. That's the only stuff that is worth getting, without setting any artificial no-crafting limitation on yourself.
It doesn't necessarily need to be better but it could be unique. Like the daedra quest rewards have unique enchantments, sadly the weapons stats svck.
I think the problem really is level scaling and the freedom to do whatever you want at any time. I think some things shouldn't be possible until you're stronger and they should have unique rewards that reflect that.
