Roper is pretty luck-based, but mostly it just doesn't have as high a skill cap as other schemes. In RR, elite, inter, BnG, I feel like I've always been able to improve a little bit each year, but roper just kind of stagnates. I've lost most of my interest in it since there are far better schemes out there, the only problem is that it's hard to come up with a similar enough replacement for it (if that's really necessary, which I'm not so sure about).
But I agree, we should look for alternatives. Even wxw is starting to look better to me, provided the map is difficult enough. My main beef with the scheme is that all the maps are quite simple, if we had some less linear ones that required slightly more difficult roping, it might be a viable alternative. And you could make it more roper-like as far as weaps and crates go. This discussion certainly has happened a lot though, and it probably won't lead anywhere, as usual >_o.
