Kill based scoring is all fine, but literally knowing knows this especially in a matchmade grandmaster strike, and it is nearly impossible to get an A score. What’s worse is some strikes like battleground oracle where you literally can’t kill the boss without waiting for 3-4 waves of champions to spawn. If you kill the boss too early, you get slapped with a C grade. Please change this to objective based scoring like Solo Ops and Pinnacle Ops to avoid user confusion.
