Not even MMO. I play Apex Legends, a character based BR. There is a ranked mode where each rank have an entry cost and you get points by placement and kills. While it’s a team game, the entry cost was so low that you could play aggressively - killing a few people and dying soon after - or survive by hiding - ratting - and get to a high rank easily. It quickly became a solo game, where people abandon their team to push fights they can’t win, hoping for a few kill, or leaving their teammates in fight they could have win otherwise.

They’ve just changed to a new system where you have to get both high placement and kills in order to rank up. That means relying heavily on your team to win the fights or strategizing rotation around the map. And some people are still complaining about being forced to play as a team in a team based game.
