Are there connection problems or is the game finally dying? I played a few pvp matches yesterday and most often than not could never get matched up with full teams. Not only that, no one would ever join either.
I know a lot are doing trials, but I never thought that would matter. Shouldn't reduce the numbers from other pvp activities.
Actually, heroic strikes were the same way. Sometimes I was only matched up with one other person, couldn't get a full 3 man team.
This has been my experience in PvP for a while now, many games, even the daily and weekly which you think would be full of people playing for marks, don't start with full teams. Mayhem Clash last week was the worst, every game I played started with less than 12 players, usually 4v4, it was ridiculous.
