Bugger all to do with that, more to do with the fact that servers don't scramble teams enough to have a decent game.
It amazes me the amount of **** players spout when playing this game, shoot down a jet chimp with an LAV and apparently you're a "camping noob that's not playing properly"? WTF? The anti air systems in this game are laughable enough as it is, aa missiles are virtually useless so chain gunning a jet to the ground is a "noob tactic"? Are jets only allowed to be shot down by other jets?
Complete joke, dice basically gave in to the air jockeys and made aa weaponry for the most part useless. Stingers should be much more lethal than what they are but dice made them far too slow moving, slow to lock on, crap lock on range and put ecm into the game that's meant to stop lock ons but also doubles as flares. And the nerfing was all to do with the crying In the first few days of the game when people were still in the process of getting flares etc, and were being shot down quite frequently by stingers.
Then dice went into "balance" mode with their patches, 1 patch seen stingers totally broken, the next seen them easily out-turned by jets, the next nerfed their lock on range to the comparable size of a gnats ****, and after that they sort of made them how they were at launch but by that point they had ignored looking at ECM on aircraft and they've been all but useless since.
Funny to say but looking back I had much more fun in bad company 2 where air power was limited and it was ground power that won most maps. If you're rolling around in a tank in this game you might as well have flashing lights or a sign up waiting to be shot to **** by rocket pods.
