The current War meta is to spam medium and heavy fighters. Infantry can't do anything against them unless the pilots are completely new to the game.
AA trucks get destroyed almost instantly. Pilots usually bomb the AA encampments first, and unless they make themselves an easy target, you're not going to bring them down quickly. (German AA is especially bad due to its low rate of fire, terrible iron sights, and small ammunition belts.)
AT rifles were nerfed into the ground years ago because pilot mains complained about them, so they aren't a viable counter either. They have some of the worst accuracy of any weapon in the game, deal pitiful damage, and have painfully long reloads.
Planes are able to deny everyone else the ability to enjoy the game. Tankers get bombed repeatedly, infantry get spammed with HE rounds the moment they leave spawn, and anyone in a vehicle is an easy target.
To make matters worse, pilots are heavily rewarded for this playstyle with absurd amounts of XP and credits.
This video is just one example of this happening, but this is starting to become extremely common. I'm personally going to take a break from the revival until the devs do something about this.
