This sounds vaguely familiar; wasn't that PS4 servers? I played on PC and never had those issues people were upset over.
Yeah on PS4,
General bugs that i'd never seen in a COD before
(this was basically permanent with that weapon, I stopped playing about 3 weeks later in late February and it hadn't been fixed yet.)
and most of all the late spawn crap, literally every match half the team started in spectator mode for a solid minute before finally spawning in.
Made everything but TDM unplayable for me and my friends(it still happened in TDM as well.)
Took until February to fix that.
