There is no reason to take flex que seriously
When you get 3 mans who either try as hard as possible or troll and play off role and play like its normals. There is 0 inbetween. The definition of a coin flip game mode. I would rather have teambuilder or ranked teams. Flex que is just terrible by design because of the playerbase. Its basically normals. Esp because of how wack the matchmaking is.
Actually I found a reason to play flex seriously. Play with 5 friends to get chally borders as a troll lmao. Thats about all the game mode is actually good for. Getting something you cant achieve normally. You could do this in ranked 5's before but it was much harder to do so.
