It's a team mode flip a coin pvp kind of thing, I don't think there is much about looking up deaths, kills and damage can do you anything positive, sometimes a match get someone who has their game crashed or they just disconnect, there is simply no way you can actually win that fight 4 vs 5, it's simply impossible, even if you have the top 10 players in your 4 team, that are known for being extremely sweaty, the balance when one player is gone simply melt down quickly, you can easily notice how a one player can be downed in a matter of a second if like 2-3 players focus all their dps on that one specific player, which most of the teams don't follow, in other competitive pvp games such as CSGO, LoL, Smite, or Overwatch, you can still push and try harder and sweat to actually win the match if one player disconnected or quit, hell even one "skilled" player can actually carry the team to win that match, why? because "Being skilled" plays a huge factor in there, and these games are at least designed to have a competitive sense to it where good players can shine or at least do something or even pull a miracle, here? you just need to flip a coin once your queue pop and pray to the RNG gods that you will have a team that will actually try to win and not tilt and spam nice job after 1 of your team die in the first encounter or if the enemy team reach the first check point first, and yes I did lose some matches where I literally had the top 5 players in the leaderboard in my team, and you know what? they were terrible and playing like normal players you would meet in bronze, just trying to cheese the pld cover the most.
Speaking about my self I made it to crystal at the start of season 2, and you know what I did, I literally grinded matches, I was hard stuck in gold for quite sometime like a 4-5 days, then I started lucking out and made it to diamond with ease, then I stuck for 2 days in diamond and then lucked out and hit crystal, it was all RNG and luck, same as when you roll for your weekly loot, and hope you get a 90+ and then you roll something low as 10 or something, this pvp mode feels the same, the people who are all about "skill" in this easy to rank up system are full of you know what.
