Feedback about helicopters

Hell no. Helicopters are the worst part of this game. There is almost no respawn timer on any vehicle. I have tons of clips of me and my squad just doing anti-aircraft all game long with nothing else done but trying to kill Helicopters and as soon as you have them down you see two more coming. I have seen 4 helicopters at one time killing one objective. They are so OP it's not even funny. YOU ARE LAUGHABLE. Thermal ah yea so there is no hiding as an already weak infantry that has very little countermeasure to helicopters, to begin with, let us just make it more of a fish in a barrel game for you. 3 missiles yea because I can just keep getting missiles from supply packs oh wait no I have to kill myself to get more missiles to shoot one down. Also, they just fly off out of distance and repair up over and over. all vehicles need a defense nerf. Hovercraft takes 3 rockets crazy its made of rubber. Tanks by the time I shoot them 3 times then die spawn back up they are repaired. In some games I just sit and take out vehicles the entire time shooting 3 times respawn shoot 3 times respawn and still never run out of vehicles to shoot without moving to a different objective. If you would like some youtube clips of how it feels to be on the ground let me know I'll upload them.
