Preface: I play Air-RB on the US server, BR 2.7-9.0.
USA teams are constantly so bad to the point they ruin the game.
Most of the time you just have to make sure you play a country that doesn’t get paired with them and it’s a win.
The odd time I play a USA plane, the games are a massive struggle. I’ll watch 1 or 2 people get teamkilled off the runway, while the rest will fly straight in at low alt to full commit head-on, or turn fight Zeros in their P-51s.
The only fix I can think of for this is splitting them onto both sides to share the burden.
