@MrDef3ctiveI am playing solo all the time. My random teammates usually are so bad... zero help from them. Like in last match we were 3 vs 2 in last fight... i am pinging enemy location and waiting them, but they are not coming. I am taking down one and fighting against second, but it takes like 10 seconds for them to join fight (even if they were very close), while enemy who was knocked used gold shield and while i was healing my team mates died 2 vs 1 and in result we lost.
In rare cases one of teammates is good (at least by banner stats), but such players in most cases hotdrop => die => immediately leave and again you play solo.
And here is one more HUGE problem. Players leave because there is no punishment. Why wait when teammate will respawn you, right? Much faster is leave and join next game.
