Park will probably be really nice once they align it more towards entertainment for kids and civilians and less towards adventurers or OP beings. That and by the time they're done the testers will be able to take out a group of A rank monsters bare handed without help while wondering what the big deal everyone is making about it. BTW Anyone know what kind of potions they were drinking? Although things were scary and dangerous they didn't seem to have been injured so healing potions probably wouldn't do much. Stamina, energizing, and mental fatigue relief potions would have to be high class and consumed in quantity after what they've been through.
