Yes, I think COD is in trouble. The new stand alone game still has no details on it, and I'm guessing Warzone isn't going to be radically changed.
I see lots of suspect things in Cold War, but it is hard to tell with all the lag. Sometimes people seem to know where you are before, but sometimes there's a bit of lag and you are just behind. I'm positive I've seen some cheats. When people are running around with high recoil SMGs and laser beaming across the map, you know they have a hardware cheat.
I'm pretty much only buying/playing games with good anti-cheat. If Battlefield doesn't have good anti-cheat, I am not buying it. I've been playing R6 Siege, only because it has one of the better anti-cheats. Even then people still get away with stuff.
