Summary
Fully Dedicated Servers, no sign of Listen Servers (COD has never used P2P)
VOIP (Game Chat) continues to expose player IPs
In-game latency widget is inaccurate
No HUD indicators for network performance issues

verage network delay for 6v6 and 10v10 are worse than Black Ops 4, Fortnite, PUBG, Battlefield V, Overwatch, and CSGO. Ground War (32v32) average network delay is also worse than Blackout.
62hz tick rates on Domination (both 6v6 and 10v10) and 21hz tick rate servers for Ground War.
Devs still don't include some kind of icon like Battlefield, Rocket League, or IIRC Overwatch to let you know if there's server/connection issues.
Like players on /r/ModernWarfare pointed out, the ping numbers shown on PC were in fact broken.
All the games he played on were true dedicated servers. Voice chat was VOIP in the background though, which allowed you to see the IP addresses of everyone in the game (even if you disabled the voice chat).
Connections favored the shooter. So shooting felt good, but often times the person being shot at would experience those instances where they felt like they would die instantaneously or after they had already gotten behind cover.

This explains why I had such a horrible experience with this game.
