Can't get past depth 3

I've been playing deep of night for a couple of days now and I've reached depth 3. Must have played 20 games in this level by now. How do I get past it? Every time I make some progress, the game will just match me up with one or two bad randoms who won't cooperate at all and we'll just lose the game before we even reach the last night. I'm not good enough to carry my games (And it's not like my teammates will even hear my calls since they prefer to keep dying to the same field boss by themselves). Should I just play solo? Is that the real way to go? Any advice or tips are welcome. I'm genuinely trying to get better at this game.
