It is easy to see that the opposing team has 13 aircraft with a BR of 11.7–12.0. Meanwhile, my team has only 4 aircraft with a BR higher than 11.3 (three at 12.0 and one at 12.3). I don’t mind being uptiered, but it needs to be fair. It wouldn’t be an issue if it only happened once or twice, but it actually occurs very frequently.
