There are only two options, (1)play with premade and die in boredom while corpse camping enemy team at graveyard, (2)queue solo and play as a ghost at graveyard.
Got same feeling, every bg this games get more and more dull, have no idea how these premade teams get fun from completely smashing opponents, having such huge advantage over enemy team is so boring, yet so many players get fun from it, what kind of people get satisfaction from killing enemy while zero challenge?
I'm aware that there exist people with defects and deviations, who love to kill people with absolutely no chance to defend them self, but wasn't aware that there are so many of them, like 50% of server.
