We play regularly, all on PS4, except for one of our friends who plays on PC. When he's not around, we disable crossplay, and the game is real fun. We play mostly Ground War.
Now, the moment we enable crossplay to play with our PC friend as soon as the game starts, the enemy is taking Charlie. How the hell? Or I'm behind a concrete wall, and get headshot by a sniper from the other end of the map.
Just today we decided that we won't be playing with our friend anymore, and he's trying to decide if he'll purchase the game for PS4 to be able to play Ground War with us.
This is the most ridiculous game in terms of hacking.
