It feels like your spawn system is designed to force closer matches. Every game a team builds a substantial lead or whenever someone goes on a big kill streak, suddenly the game reverses momentum heavily and it feels like the winning team gets spawned apart and near enemies over and over.
I am not sure if they are really are ‘rigged’. However, There were times in BTB where in a close match my whole team was respawning far away from the objective which gave the opponent time to capitalize on it. I think that’s more on the lines of being unfortunate that most of the team died during an important part of the game.
