Lag Spikes and Disconnecting, Multiple People on team.

Just had a game where several people in my game were typing about experiencing large, unplayable lag spikes at the same time during a game. It then disconnected me from the game, and I was unable to reconnect for several minutes. When I tried, the option to reconnect went away, and the game didn't appear in my match history. 30 minutes later, the game appears in my match history, I lose LP and get a leaver buster warning. Since multiple people across my team and the other team were all experiencing intense lagging issues throughout the game, and the inability to rejoin the game once it disconnected me, I think there should be loss prevention.
