They're doing their best to make the matchmaking better, but it will never be perfect, it can't be. People choose to go afk or do stupid things and in other cases some simply dc unintentionally, the new match making puts you closer to people of the same tier, in other words, the higher your elo rating, the less chance for you to encounter a troll ingame. The higher your skill tier, the higher the chances of you being matched with serious players.
