This thread is to try and understand the unit drop rates for each kill. First five missions, drop rates for the required unit are close to 100% but than it becomes harder.
Level 8/10: defeat Saboteur Lieutenant (Boneyard) requires 6 kills (5x68 energy per kill). I needed to 14 kills to get the unit 6 times. The drop rate here is less than 50% (6/14)
I want to know what are the drop rates everybody else is getting?
