Normal gaming 
Some people here are normally skilled gaming humans! We can't all be 100k+ gamerscore demi!!
Ideally "normal" mode in games should be balanced for the average gamer, aka. me, so I also play every game on normal the first time. If it's too easy or too hard and I should have chosen a different difficulty level, than that's the fault of the dev.
I mean in this case I don't play this genre and the last PC looter I played was Diablo 1 and I never even got all that far. Normal should be for sorta-genre-newbies like me!
But yeah, I'll try it again on hard. I like the game but I'd like to have to care about what types of enemies I'm fighting and do something different to strategize against them instead of just running up to them and clicking.
