I was playing on adept (not incredibly high I know) and I went into a random dungeon (forelhost) and I got destroyed repeatedly by loads of draugr deathlords. This happened countless times btw - I'd say about 12 times in all - before I did the crazy thing and lowered the difficulty.
Well I waded through the later draugr with ease. And I was getting truly amazing loot too. By this point though, due to my drunken stupidness, I had forgotten that I had nerfed the difficultly and was extremely pleased with myself for destroying everything.
Anyway, my point is, why do some people play the game on the highest difficulty? I can imagine its a truly horrible experience.
Ps sorry if that didn't really make sense. My blood alcohol content is crazy right now.
