Second edit: 3 strikes in a row now and haven't even got an armour drop let alone a class item which is the focus, let alone a T5 with the stat distribution that I'm looking for with my ghost mod. How is this working as intended

Edit: i know rewards are tied to score, but we kill every enemy in the strike, complete every objective and barely even reach A, let alone A+ for a CHANCE at T5 or S(+) for guaranteed T5. There has to be a better and more consistent system for getting tier 5 loot from the quickplay ops because nobody will run regular GM strikes
