There are so many more possibilities with the crafting and harvesting systems. In the end. The end result falls upon you the creators and developers. What you could do is make each roll worth so much crafting value and once said item is crafted. They could either then use it themselves. Give it or trade it to another player. Or sell it to a market worth so much. Also, you could make certain chests or places that are other wise empty or have low item counts have crafting material and completely avoid having to harvest and roll for that. However there are a lot of players who I am sure.would love to roll to harvest. And then there are so many possibilities with salvaging and enchanting
Let's not and say that we did. Not every single game on the planet needs a crafting game *rolls eyes* but at the same time it does have a crafting mechanic LOL! But it's never enough is it? Ye! Of Entitled Gamer *smh*
