I think this map is mainly just more proof of the phrase "Quality over quantity"
Anyway, the last point is possible to cap, but only on unbalanced teams. its not as bad as gold rush though, you have at least some moral of hope to get to the second last cap point.
And personally, I think the maps should have different explosions, but this one does feel abit... lacklustre. With goldrush, you feel you've actually done some damage with it, on Badwater, it just feels like... "Okay was that all we needed to do?"
