Your Overwatch - one of the Youtube channels which Blizzard has paid to come and report on Blizzcon and Overwatch League - made a video discussing the counters for every hero.
When they got to Genji, they admitted it: Genji has no counters.
I’ll admit that genji is overtuned but Moira and Brigitte aren’t bad against him. Sym turrets are fine too esp if they continue to buff her beam / survivability / tp speed.
Em, no. Why you would want to nerf him? Sure he is obnoxious and players you encounter tend to think they are pro, leet, smarter and better than everybody else because they play Genji but it boils down to your own skill. If you are better than Genji you will beat him.
That’s not what they said. They said you can try to jump at him with D.Va and Winston, but he can outplay that strategy. The alternative is to pick heroes and try to kill the enemy faster than he kills your team - which isn’t a counter in any fashion and could be said about any hero in the game. If that’s Genji’s ‘counter’, then Genji has no counters.
That is what they said, though. Literally every statement they made was with the qualifier that “Genji is playing a survival focused strategy, playing solely for Blade, and doing it perfectly”. He is otherwise easy to kill, and a Genji that is only playing for Blade is disadvantaging his team when he doesn’t have it up.
If “he has no counters” was the message they wanted to portray, they would not have described ways of denying him value both offensively and defensively.
Saying Genji is strong is one thing. Saying he has no counters is a completely different kind of delusional. Winston, Brigitte, Moira, Doomfist, Mei, even Pharah to some degree. These are heroes in the same game. They all have a reliable way to kill Genji through deflect and all apart from Brig and Mei have a way to keep up with him after he dashes.
Winston doesn’t counter Genji. He’s just more inconvenient to fight than other heroes. Winston is way more effective against pretty much every 200 hp hero than against Genji.
