@EA_David "We then gathered enough data to prove that servers don't think clients are timing out, but clients think servers are timing out. That was a strange finding. We also verified that we aren’t launching matches that are partially full - so code:leaf seems to hit every single player on that match server, not just some players."
This is not always true. My roommate and I play on Xbox One right next to each other. It is a regular occurrence that one of us gets Code: Leaf and is kicked back to the ready up screen while the other is sent into a game with missing player spots. Code: Leaf regularly affects one or two people in parties while sending the remainder of the party into games with missing spots. The assumptions you are making here are demonstrably not always true.
