I'm a sneak attack kinda guy...love slitting throats with my dagger. If I get spotted, I like to either pull out a 2 handed sword hard hitting power attacks to kill quickly (especially ebony blade) or pop on a sword and board to absorb some hits with blocks while whittling away at the enemies health.
I have played many combatstyles, but I usually go for dual spells, or weapon/spell. I am a huge fan of magic types no matter what game I am playing. I have a level 81 bound bow pure mage character that I still load up and play at least once a week, even if it is just to decimate the city of Solitude etc.
I love sneak attacks, where no one notices like assassinations. I also love when I'm fighting a dragon and it does that little screen shot you can't control and you jump on top of their head and stab their eyes out! http://www.bkserv.net/images/Tongue.gif
