I brought this up in discord a week or so ago, but i wanted to bring it up on the forums so more people could see it and maybe think about it.
My issue is with people abusing a bug in game that allows the helicopter to fly with its rotors spooled down and silent. People are glitching their helis by breaking the blades and flying into the AO before the game can reset it. The sound/movement on the blades seems to only be restarted once they adjust the throttle, meaning they are able to fly and land helicopters in the middle of the zone completely silently and the only sound you eventually hear is at is pulls out.
This gives a huge advantage to the the helicopter landing since players on the ground have no idea one is coming in, making it so they don't have time to shoot at it as it approaches. The fact that the silent engine/rotor stoppage is the result of a purposefully in game action to abuse a glitch i think should make it illegal. I have a hard time seeing as how it can be justified when any other time a player purposefully breaks the game for an advantage its frowned upon.
So just wanted to put it out there, get people to see it and read about it. I see more and more pilots doing this in game.
