Sounds like you have trouble leaving a level at 2 out of 3 stars. I love your passion. In this game there are two methods of overcoming "difficulty" one is battling the RNG as you have, the other is being willing to replay missions when you have better load outs to get your 3rd star. To some the latter feels like cheating. But both increase the amount of time you get to enjoy our still limited number of levels.
