Oi, ok Mob Properties is both very powerful and a bit of a pain to work with. For now, I am removing Zombie Awareness and enabling special mobs by default. I have disabled all the more objectional and pita Special Mobs, leaving mostly variations on vanilla mobs. For instance, zombies are 70% normal and 30% giant/brutal. It should be balanced well enough to be fun without instant killing you with over powered mobs. Creepers are virtually untouched, although 1% of them are going to be mini. We will try this for a version and if it isn't too objectionable I will stick with it.
