If people give you hard time, just open the scoreboard in-game from top left of your screen and click the mute button on offending players, it also ignores them in chat and keeps them ignored if you'll ever end up with them again. Don't hesitate to use it and remember, because you will be pretty low on the matchmaking ratings the people who get angry at other people for doing mistakes are often players who have played maybe hundreds of games and are still matched with beginners. Don't think they're any better than you, they're just people who never learned to do anything except blame other people.
Also, when you're picking a hero there's options to filter heroes by their roles or beginner-friendliness. And ignore Kuntantee, he is never helpful.
