You mentioned reflexes, i use reflexes a lot. All my guys are specially trained for reflexes (rippers are great for this). Helps during the storming of UFO (sad that the wolf decrease reflexes), if there is an mk3 weapon in this phase, then even ambushing high-ranking fighters are possible. It works well when wave of rippers or xenomorfs attacking when storming a terror ship.
Interesting thing: when xenodrone stand against a wall of waiting riflemans with all TU, he often dont move next turn. Dont know what it is, does he scares about reflex shoot or just some sort of bug.
Curious, what about mechanics of reflex? How reaction modifier and weapons range works? What file is responsible for that?
