I agree with Wicht.
Those that are going to cheat will do so no matter what changes we make to the generator.
I like cleaning up the styles and making relevant defenses for everything....
We should purge some of the Western sounding styles.... Unicorn just feels wrong to me. Manta Ray is totally out there. And although it is more genre-specific, I think chopstick is lame. I wouldn't miss it if it went away.
If someone's signature style goes away, they should get to pick a replacement.
I think there should also be 1 general defense for each category: animal, weapon, beast, plant, weather.....almost like wild cards.....
