Of course you did, you're a bloodthirsty slayer!
I did finish Nightmare quite well too, but my goal was to play Hell Mode too (from scratch) and that's a lot lot more difficult because without that one reward from one of the modes (forgot which) they don't heal up as much after every fight.
I dropped it then though because of limited time, and then I rather felt like replaying TBOL.
Not sure if I'll continue that playthrough of DSC one day. It's not that I couldn't do it, it's just that I don't have the patience.
