Mark I had thought about that possibility. Like the strangers collecting blackrock that lead to the destruction of Haven. There WILL be a bad results ANYTIME blackrock is amassed in large sums, but still no matter the "STORY ARC", it is bad form to flood the market with this rare type of resource when the old type "seems" to be able to be used in the same since.
Also it is called "Blackrock Stew"
Most things that have a name in front of stew tend to contain that as the primary ingredient.
Rabbit Stew, Chicken Soup, & so forth.
