@D-Man3847The amount of rockets it takes is irrelevant. Flares, lockons' fundamental need to lock on, helicopters' mobility, and their ability to go OOB are all enough to make things ridiculous. And this is not even a new issue for BF, attack helicopters were farming infantry on Siege of Shanghai too, though at least IIRC the AA in BF4 was actually decent on other maps.
I've gunned for an attack helicopter, on the periphery of Kaleidoscope, my pilot hiding us behind the buildings - the ones between A1/2 and C1/2 that snipers love to sit on the little indent of - every time we got locked, only to pop out later and farm the infantry on A1/2 for a few kills.
We were getting hacked, hit by a stray lizzle, locked as soon as we got out of cover, and that did not stop us, only delay us, because the only weapon infantry have to actually consistently damage helicopters is the NTW-50, which is terribly underpowered while requiring a higher amount of skill. And even if they did use that, we'd just repair it (like with the stray lizzle).
You can have all 64 people lock on, it's not going to do anything when the helicopter flies away. If 64 people decide they're chasing after a tank, that tank will likely eat a 35 damage rocket, THEN pop APS, kill 0-3 people and after that finishes it will die because it's not mobile enough and it can't run away to where infantry can't touch it, generally.
Exception being TORs at spawn or some extremely faraway spot on a map, which people usually dislike as well. The TOR should not have the Maul ammo type and you should not be able to shoot while in spawn, like in Battlebit. On Conquest. This does not have to be a thing for all gamemodes.
