i would really love a mod that makes the difficulty slider just increase enemy damage and leave their health and my damage the same... i really hate it when i have to pound something for 5 minutes to kill it, on harder diffculties the combat in skyrim just becomes reaaaally slow..
That's why I don't play on master difficult. Only in Expert.
I hate having 5 minutes do kill an enemy that could kill me in 5 seconds. That's not difficulty, it hinders and insult your abilities.
In Expert I kill dragons with... dunno.. 1 sneak arrow shot + 6 arrow shots and it's enough as they kill me with 1 fire breath.
I really think harder difficulties should give the NPCs more intelligence. You know.. They detect you easier but not magically, they have combat moves and enhancements, better gear and so on.
