I'm here to give the idea of having two categories for each sub-category of the Diamond Casino Heist. As the title implies, there'd be a category for buying preps (it can be just 1, it can be themall, doesn't matter) and actually doing all the missions the player feels like doing, without buying any. I'd say this way more people would start runnig it, as the meta right now makes the player use lots of money, which can discourage someone to run it, as they don't get their money back doing the heist.
