Good rule of thumb (for me at least) no matter how annoying a 3v4, 2v4, or even a 1v4 is, don't leave the match. Just stick it out. Too many ditched matches or disconnects in a short period of time are going to result in a suspension. This had happened to me once before I had gone to a wired connection. I had left a match once (can't remember what specifically happened with that match, but shortly afterwords, I had joined another match, but that time, I was disconnected half way through and kicked to the Destiny 2 load in page. When I got back in the game, I was awarded my first suspension for 30 minutes. Have not had a single issue since switching to a wired connection.
