So tired play in bronz-gold , same troller with you 3 games and lose 3 games ,that was normal. its almost no possible rank up without premade. 4won 4lose 8won 8lose. and there are always trolling player do nothing and almost 100% lose cause exp. shared for team. feel sad lose Not because of a playing mistake but just someone will carry you to lose and u all know it from beginning .
Get used to it. That’s HoTS.
Same experience in Plat, Diamond, Masters and GM. The game quality doesn’t get better. Games in Masters are like Silver.
Its rly about blizzard but not just this one game. i played 15years games with blizzard. but feel they didnt follow the generation… imagine WOW can change a engine and remake from new edition… but they do classic mod turn me to lvl60 and TBC . all update make me play 1 month and AFK… and never think about go back… 
.
in hots at almost every level you get people that have no idea how to play the game.
today I had a game where tank was late for most tf’s and then complained that the backline wasn’t doing enough damage. oblivious
