It takes TIME to farm for a chance vs a guarantee. Your opinion is that it takes seconds, that's incorrect. Even on the Tiger Strike of Mars, most people skip the first room, kill the generals, tank and then the room + boss, they skip the rest. That run, with a solid group takes 20 minutes. - I've heard of it being done by 30's in 15. Your 5 minutes is 1/4 the time it takes me on average to run that mission for guaranteed engrams. You're statistically wasting my time. There's no argument to be had that's mathematically sound because per the math, you're wrong. Your farming isn't mathematically worth my time. - That's a fact. Do the math yourself. The bottom line is that killing every single mob in the run, is a total and complete waist of time compared to the guaranteed prospect of 1/2/3 rare engrams with the same % chance of rolling a legendary. Disprove the math for me if you want to retort because your argument is a straw man until you do so.
