Idk what server I was just on but holy crap, I just bought the game (its been a long time since I played it years ago on console). I started playing operation I think. Well, I got into a game and I had 161 ping and every time I was literally spawning in a cloud of smoke and being deleted.
I believe it was smoke grenades and non stop sniper flare guns. I was just getting headshot through the smoke and could barely get around a corner. Went 30-37 kd on that game. But then,
I decided to chatgpt it and realized I can filter the servers for NA and then found a good 41 ping server with good admins taking care of it then I actually started to have fun, went 25-15 kd. So, that first server must've been filled with veterans or they were using cheats or something.

Whenever you see a spot flare landing close to you,just relocate
asap.In
99% of cases it's followed by a sniper shot.
