I'm gonna say that too many people use the work pick.
9/10 times, if one dies, it could have been avoided.
You engaged more fighters than you could handle at once
You lost too much E and couldn't properly disengage
You stayed long beyond the time you should have disengaged
You got target fixated and didn't check your six, or expected others to do it
You got target fixated and didn't care what was on your six
You overestimated your ability to finish off the guy in front of you before the guy on your six could finish you
You underestimated the E state of the con you were saddled up upon and he hung you up like a picture for his wingman
In the MA, one should never-ever assume that you are going to be left alone in a 1 vs 1
