I like the new Ranks! Much improved, don't you think? Although "minor" seems a little underwhelming. Consider Risky, Unsafe, Perilous, Unpleasant, Hazardous, Dangerous, Precarious, Menacing, Threatening, Treacherous, Distressing, Injurious, Nasty, Bad, Horrible, Terrible, Wretched, Ominous, Gloomy, Foreboding. Trying to come up with a thematic word that also fits nicely on the shorter, easier end of the Rank scale. Or leave it as Minor if you like that most.
