Many things matter when playing an arena shooter, like how the team talks and what the best strategy is. Like in Overwatch 2, everything plays a role in the team's success, which is why playing solo is a bad idea. The main thing about these games is the teamwork and how each character helps the overall objective. When they are playing a role, like a healer or a tank, everyone's doing something, which can make the match easy. The latest entry in the genre, Gundam Evolution does this very well, by forcing each player to pick a role, for something that'll help the team win.
