Karnak is 100% right.
Killshooter works, and with wonders, too.
So why change it? How often does one meet kill shooter induced death anyways? I've both caused kill shooter deaths, and been subject to such deaths, but it's so rare that I hardly notice any so-called 'drawbacks'. Not to mention I apologize with deepest regrets, when I ever cause one.
Being subject to kill shooter, in whatever end, just simply means you have a sucky SA.
It's not just how many enemy planes are in the area that matters. SA includes the awareness of all of your surroundings - the whereabouts of your friendly planes are as important as the whereabouts of enemy planes. If possible, knowledge on the personality, skill level, and tendencies of your fellow pilots, are preferable, too.
Just when do people get KSd?
More often than not when hordes of friendlies chase after one plane, groveling for a single kill. KS, in reality, rarely ever happens in fights of equally matched forces. In other words, you would almost never get KSd during a well formed and structured clash of planes, where a clandestine friendly really ACCIDENTALLY crosses your gunsite.
It happens when everyone is simply blinded by the greed to get a single kill, hordes of people chasing after one plane, that they forget everything else. KS is simply a result of target fixation, glaring stupidity, indifference and disrespect toward your fellow pilots.
And as Karnak said, precisely because the results are so lethal, that it makes us check twice, look around, try to avoid it. KS is like car accidents. It is the danger of it that implies to people that they should watch out themselves. And if everybody is careful, accident rates will naturally decline.
Of course, there are people who aren't careful. People who are wreckless, and unaware of what happens around them. That's why there are automobile accidents, and that's why KS victims appear. Both the KS and the KSee is equally in blame, when that ever happens.
Doesn't matter what you rank at, how much your skill is, how good a fighter pilot you are. If someone gets shot down because of KS, they deserve it. The one being KSd, is not really an "innocent victim" at all.
Also, the one who induced someone's death by KS, is most likely to be flamed. People get angry against such people, and most likely he will be victim of such consequences himself - since the same kind of people will be hording in the same spot most of the times, wrecklessly and pathetically groveling for a single kill.
KS works. You can hiss and moan and blame and flame the one who gives you KS all you want, but as long as the system is there, you will be the one who is going down, and it will make you think twice next time. It urges people to stay responsible for their own safety. Which in turn, dramatically lessens the idiocy of people shooting at their own planes.
If KS is such a problem for someone, I suggest he better correct his flying style, first.
