Ok. I love the chef one.. That cracked me up. But the chemist should be called paladin, because chemist makes potions, doesn't heal other. Paladins are healing warriors. (heal teammates while fighting)
I don't fully understand the concept of having golden nuggets. Is it to fill up space?
You should have a (choose one) "Master, God, Sensei" chests, with over 9000 power armor and over 120943819202184 power bows and swords.
You should make a PvP map behind the chests, where people can use the chests to fight others.
Ask me if you want more suggestions :)
