Why does 1 griefer or bad teammate have to = autolose?

Worst thing about this game. 1 person griefing or just simply being useless makes it nearly impossible to win the game.
You’re more likely to win if they just leave and you get a bot.

Why this game have to be designed this way?

6,5/10 game no comeback mechanics

6.5? 6.5 was when blizard employ people. Now they employe only brai.dead animals and gameplay is 0.0! five-six times a raw drafting system gives to you same ppl in team. Until to blizard studio people dont come back there is no chance for better. They killing every game what previous studio done (diablo, overwatch, wow, they will destroy heartstone too - just give them a time).
