Echo is the latest hero making her way to Overwatch, and she's quite the powerhouse. She packs in a offensive features, but she's quite weak when it comes to defense. In an interview with Polygon, game director Jeff Kaplan talks about trying to strike the right balance for Echo.
"I think the balance challenges revolve around making sure she’s not too dominant in any one situation, and that she has some vulnerabilities."
Producer Gary Fonville said that when it comes to balance, sometimes it's the players who show Blizzard the way.
"Sometimes the community teaches us how to play the hero. I think Overwatch League will see some really great moments and strategies that we may have not encountered internally, and how best to use her.”
