The problem is that I don't think ever had 3 stingers fired at me at once and the last thing the game needs is more engineers to make up for the nerf. I'm thinking stealth to keep the remaining stingers and heat seekers off me and a fire extinguisher to repair from 2 missile hits and guns.
On the flip side ...... should jets and other air vehicles be invulnerable.
Thats the the problem with these games ........ somebody likes jets, but they don't like the counter measure ....... somebody likes infantry but hate vehicles.
Nerf this and nerf that, it will never be balanced ....... not everyone can be made happy, there has to be a level of compromise.
