It’s easy, when you enter games people do not respond in chat or don’t play as a group.
As a DPS you can’t contribute much in most BGs that will change the outcome. When you are a healer you get hate speech… why queue for something you don’t have control over and / or get hated upon ? Fun? nope…
At this point they better retire anything SOLO and get back to the old Arena / RBG system
Climbing ladder is gambling! Every win raises your mmr 50-100 points and lose -50 - -100.
Getting a win streak is the goal here, like 20 wins with 5 loses. Then every game you play will increase your rating by +21 and you do not lose any points when losing a game(because your rating is so much below your MMR). Only downside to this is that you get tougher players (those who can carry their teams in low AND high ratings). So eventually this win streak ends unless you start to carry. Carrying feels almost impossible because game mode is so fast and there is no communication, typing strategies in the chat is useless because most have disabled chat. Disabled chat is smart, because people like to type only about how they feel about their team mates after realising they are losing. Stressing about them is waste of your life.
However, if your winrate is negative, your MMR goes down to 1500. If you lose a game when your mmr score is 1500 and your current points be eg. 2000, you can only lose points and not gain anything until you hit a new win streak and get more wins than losses. If you wonder what makes it gamble, ill tell you some: random maps and random compositions of classes! Some classes autowin some maps (like stealth classes on base maps or ferrari monk in capture a flag maps). So good luck everyone hitting that win streak on one of your alts! Unfortunately it is not possible right now because average game lasts like 6minutes and que times are 10-30 minutes
