I personally think the TES universe lacks large bosses, or enemies with strategies. (Like let's say a weak point on their back, that you have to stun them to reach, or when they say fire is good against trolls, they make trolls a lot more difficult, but fire actually does a lot of damage). But that's just me. It seems too much like a spam the attack button till its dead and then open the menu and then gorge on potions to heal when you're low.
I like how there ARE bosses, and they are cool, but most of them can pretty much one-two shot you if you don't heal yourself every 5 seconds.
