It didn't "ruin" anything, it was a slight nerf to scotch. From what I've seen, most people run scotch by themselves. Most of these people will probably not cap Wong's before they cook scotch and will just deal with the slight cut being taken away. It's not a beacon that somebody is cooking scotch like you're complaining about. Sure, some people will cap before they go to cook, like any other cartel, but they could also be selling it or capping it to make money. 90% of the people capping drug will run meth anyway, it's not like it's some huge gamble of what they will be doing.
