Its not only Trials, every single pvp mode and Gambit is the same, go in with a full fireteam and most of the time you play only solo players, and its been like this for years. In addition to connection quality, the matchmaking should also prioritize finding similar size fireteams to play each other in every mode, then you wouldn’t even need freelance playlists that ultimately only make the matchmaking worse because all players are not in the same playlist.
