You do, you would have to 2 and 3 cube the Fodder Bosses, and H10 Hotspot would probably be 10 cubes or more to beat at that DP. It was 7 Cubes for me at 16.2K, and only dropped to 6 with 2K more in DP. Needless to say Mobage is misleading us on the recommended DP. Indeed it was. And thos estimates too were also conservative. You would need a much larger DP than 20K to 1 cube your way through, and still have to 3 cube H10 Hotspot.
