Think its best to just remove the auto-eject feature... or prevent healing..
I think Arma engine needs to possible test a "break action" command that can be used every 3 minutes or so... Say "Alt-X" would break any animation or thing its doing. This would remove all the clumsiness the player feels. The timer would be added to the command to avoid abuse.
In this case, i could go.. eject and hit the heal button by accident, Realize "oh crap im healing", But hit the break command and run to safety and not be entirely pissed off that I died from game mechanics going run, which are unrealistic, people can change minds quickly.
