The assessment of Cocky -> Lazy -> Stupid -> Dead is spot on. I haven't gotten super far, but my last run ended because I saw a bunch of 'C' in the next room and didn't bother checking what they were - turns out gravity hounds have a pretty good stun lock. Out of curiosity, what class were you playing?

For what it's worth, if someone told me they beat Morgoth in an interview I'd probably hire them.
