I never had a problem with it because I installed the Deadly Combat mod before I hit level 10 and while it doesn't fix the simplistic combat it greatly increased damage and combat difficulty in general to a much more realistic level (plus Deadly Dragons and Deadly Dance or so something like that, its a kill animation mod that adds a tonne of variety). More elite enemies do take more damage to kill than lower ones like the normal system, but it still drastically reduces frantic slashing at something for a minute before it finally dies.
That deadly combat mod sounds great. Not that it would be of much use to me, with Illusion and Sneak at 100, I can one shot kill mostly everyone with a dagger hit (*30 damage sneak att crit) and with no problems casting Invisibility and with the chance of Pacifying everyone, it's almost a cake walk even on Master.
About the deadly dance mod, is it like this?

That's my problem as well, though it could be related to me being a battlemage with light armor who's never been to Winterhold for destruction training. Why does it level up so slowly, and why can other mages literally spam Ice Storm? I may not have a lot of health, but it shouldn't be 1-hit killing me when I'm a werewolf or don't have 80% magicka/frost resist (stacked). I know I have a mod that augments destruction but I can't one-hit kill a single damn humanoid, and my destruction's at 55 and the mage that kept killing me had 70. I'm a freakin Breton! This should not be happening.
Destruction magic for the player is extremely underpowered. While some mages will have no problem killing you in two hits (like that guy with all the skeevers in the meadery outside Whiterun), you can max out Destruction and get all perks for it and won't be able to kill a town guard without casting a couple of spells and draining at least half your magicka.
Destruction magic looks like a cool build but unfortunately it's very weak, playing at Master is just asking for pain.
