I think it will hurt OC, especially when it comes to the novice gamblers who don't want to deal with shady characters. I don't think it's a death sentence though, the degenerate gamblers are still going to need credit to bet. It could even help. You will have those novices that are sucked in, lose everything, and have to turn to OC books. It will be similar to how people got hooked by the Doctors with pain meds and had to eventually turn to street drugs when that ship sailed.
