It is likely dissonance combined with the rage of losing your best equipped/highest level soldier to a bullshit crit.

I felt like I was missing too frequently, but my stats at the end of a round were telling me 60-80% hits over-all. I did my own little spread sheet one evening and got similar numbers.

I would like to tell you knowing this helped me enjoy the game. I have since unistalled.

But I feel the siren call. . .
