Man i just asked me 150 times this question since fallout 3 when i was playing new vegas (i just never saw a game glitched like this before and im playing since a long time video games), my conclusion is that bethesda or "bugthesda" make really great games but full of bugs and glitches very annoying when you always forget to save your game often. I just still asking me why in their 1.5 patch they add new killcams instead of correcting the thousands of glitches in skyrim, just search in google. That's how when you play mage you cant have the guardian circle, for pc players you got unofficial patchs but x box or ps3....

I always try to play single player games like a PvP RPG game.

I noticed myself dancing around the enemy especially when I went into third person view during combat. I let my characters skills do the talking and not my pvp strategies. I will stand there and take a hit using block instead of backing up excessively, relying solely on my players defenses/resistance/damage, not entirely on my ability to dodge an attack.

This is indeed a differant approach to the games difficulty.
