Actually, I haven't read all of these posts but from what I have read I think that making a special button for rfs is just supid. Maybe lets just make extra button for shooting every kind of ammo at once? Maybe thats not the point, but really, that would allow you to use any ammo + rfs at once. That means that many places in many levels would be much easier to camp for example. Overpowered.

But tbh, I'm not really used to do RF tricks, but if something like that were implemented to jj2 then I'd have to learn how to use that, because thats a big, really big advantage for someone else, so I should also start to learn how to use that. But I don't think that it's good idea to make something like that.
