Don’t pick 3 starred heroes. They are marked difficult for a reason.
My family members, friends, students all do this.
Regardless of age or anything, they always pick the hardest heroes first before learning the game.
When I played my first match when OW was released, I played Mercy in King’s Row, since she was a 1-starred hero with quite straightforward mechanic. Just to get used to the game/interactions.
Nowadays kids who play (cousins + students mostly) OW start off with Hanzo, Genji, Ana or Tracer (typical ) just because they look cool or they’re famous.
I’ve met plenty of random strangers who play these heroes when they are below lvl 60 and are CLEARLY not smurfs who do this as well.
If you meet someone who’s going to play OW for the first time, tell them to play rather simpler characters first then gradually hone their skills to smth more difficult.
It’s like making a toddler run when he’s never mastered walking in the first place.
