Well, it doesn't really. CapnScurvy did make it better for FotRSU though, as compared to the Attack scope, though the differences still are not as pronounced as they were in real life, and you can usually use both without issue at just about any time. As for the buttions, I sometimes, I wish for a "go back to where I was" functionality, but then once I did get used to using short-cut keys, I do prefer it the way it is...
