The reson youre getting so many killshootings is undoubtedly because you fly into those mass furballs and chase a con with a dozen others all trying to get the same kill.
Now when AH had less people in it it was a lot more personal and people remembered your name if you kept interfering in kills (ie like you said flying between bullet streams of someone elses kill)
and soon enough your name would be mud which meant no one helped you out.Now theres just so many theres relative anonimity through the sheer amount of flyers so the game seems to have degenerated into a mass scrap with people ignoring the fact that some other player has worked that enemy into a good firing position.
The amount of times ive chased cons from 20k to the deck only for some bunch of dweebs to swoop in as im about to kill them has changed my way of flying in MA. Now i look for groups of enemy fighters with 1 or 2 friendlies around so i can finish a fight alone.
perhaps the answer is to film and post pics on a weekly 'MORON OF THE WEEK' post?

my suggestion is fight further from the masses of idiots who try to steal kills.
