Essentially. Why do people think it's normal to be able to land all of your shots in your magazine on aircraft and it do nothing? The point is regular bullets aren't supposed to be able to hit them that many times in a row which is why flak cannons exist.
Let's put it this way. Even helicopters in real life don't hover in one spot unless landing, deploying, etc. for this very reason. The Apaches had to develop new maneuvers that had them quickly firing on target while they gain speed and swoop on by. Do you see them hovering RIGHT ABOVE enemies and just sit there? No. They hover when they're really far away when there's no hostiles in range to hit them and then they pick people off. You never see them just sit there and purposely take fire thinking they're invincible.
Hell, look at BF3. You sit there and put your F-35 right over a base and hover there, you're fucked. You can get a few kills but of you're going to die.
I don't get how people don't get modern day doctrines and the importance of keeping on the move, and that plays out in this game. If you sit in one place, isn't it your own damn fault for your death? Is it messed up that some spent all their certs for something not as good now? Yes, but that's what to expect from patches in a rock, paper, scissors game like PS2 and that's why I didn't buy the armor. I keep on the move and try to stay alive as long as possible.
So you can complain about losing the certs maybe, but don't think the fighters should be able to hover right above a point and somehow be invulnerable when that's not how it's meant to be played. You're never supposed to get all 100 rounds of your magazine on target on them unless they're doing something wrong.
Edit: By the way, I'm an aviation nut who loves to fly in games so don't think this is infantry bias. I'm more annoyed by AA rockets.
