Yes and the first time I fought a draugr death overlord, which one-shot-killed me with a shout, my first reaction wasn't "OMG what bull make him weaker". My reaction was "OK...I'm going to get stronger, come back in a couple levels, and wreck his ass."
That's all well and good for those dungeon-dwelling Draugr you're talking about, but; 1) out-in-the-wild enemies are a bit different (especially when we're talking about things that aren't in obscure places, but rather along the route between two major cities), and 2) things are a bit different for mage characters. As I said before, Snow Sabercats 2 shotted me constantly (
with my relevant defensive Alteration spell going), even when I was in the 20's level range, and they also had enough hit points and/or resistances that I could blow through a whole magicka bar and not kill them (which was only even possible while my companion was tanking - and he couldn't take many hits either, at least partially thanks to their level scaling being broken). Besides that, the cats are fast enough that I couldn't out-run them, so if I ever got one after me it was basically hit Escape and reload my most recent save. A mage can't "come back in a couple levels and wreck" something like that; you might be
many skillups away from your next rank spells (my Destruction is only in the 60's now at level 41). You also have to devote points to both magicka and health - too little of the former and you can't kill the target without melee (which has been a constant problem for much of my character's life, and is the reason my 1h skill isn't THAT far behind my Destruction, despite having the Mage Stone active the entire game), and too little of the latter means you die in 1-or-2 hits against a large variety of even generic enemies.
I don't think very many of us want a game where you can hit a button twice and kill every enemy that gets near you, but some things are a bit out of whack at the moment. Early dragons could probably stand to be a bit tougher, and some other things need to be a bit weaker. Call me crazy, but I don't think anything in the game should be capable of 1 or 2 shotting a high level character in good armor (and/or using high-end Alteration magic), unless perhaps they've devoted basically zilch to increasing their hit points (whether via level ups or enchants).
