The number of times I've failed that challenge due to the targets not spawning in is staggeringly BS. I had to look up a video to find the pattern where the explosives spawn in, I follow that pattern to a T, and half the time I get to a certain point, the next targets don't spawn in and the timer runs down, killing my attempt. Sometimes the hits don't register to the explosive, sometimes the explosives launch the other explosives away without detonating them, killing the run. You need to be -blam-ing frame perfect on targets that have no aim assist, which makes it stupidly difficult for Controller players to make the attempt. Combine that with the timing required makes this probably the most BS challenge of the bunch. You managed to turn another cool concept into something that will only frustrate players and kill any feelings of accomplishment they may get for completing this stupid, poorly designed, sorry excuse for a challenge.
