For those of you who are relatively new here, the reason they implemented the "critical damage" feature was to eliminate people from shooting at wingless airplanes as they fell to the ground and stealing the kill from the person who did the kill shot. The way the model used to work, you could take someone's wing off and their plane would be un-flyable, but if someone came along and killed the pilot, or did a ton of damage to other parts of the plane before the plane hit the ground, they would get the kill because they technically did more damage even though the plane already had catastrophic damage. This is not a new issue that you just discovered...its been looked at and they have implemented their solution. Might not be perfect, but I bet you have ended up with many kills that would have otherwise been stolen from you in the past. It all evens out in the end.
