You can't blame those that are organized.
The board has been full of 'hording' 'ganging' and other 'unfair' undesireable game play gripes for a while now. While many expect HTC to change some parameter that will fix it, I think the real problem is that Kaos is being turned into order by squads. Squads take bases quickly, and cover each other's sixes, and drag and bag opponents. The response to this has been for more folks to form and join squads. Next time you check the roster, sort by squad and you will see that most of the folks in the arena are in a squad.
The order and coordination a [good] squad provides is very difficult for a single player, or group of un-coordinated players to overcome.
To me, and I've only been playing about a year and a half, the game is evolving into squad vs Squad and the single players are having more and more of a rough go. When I fly with my squaddies, kill ratio is 2:1 or 3:1. When I fly around by myself it's more like 1:1. [note to self....Fly around with Squad more]
I think some squads are just better at...well...being a squad than others.
