Just a suggestion - since you can't get XP or drops from mobs more than 5 levels below you, I think it would improve game play if any non-"human" mob is set to yellow instead of red? "Human" mobs should still attack, I think, but there is nothing more annoying than travelling through a lower level area and having some crappy monster 10 levels below you knock you off your horse.
