I will speak for myself only. Nothing suggested that Genji required buffs other than some people complaining. Genji has been one of the best DPS statistically for months and buffing him will only make him become the best one without contest. It’s similar to McCree having terrible numbers yet getting a nerf that he didn’t need and now he has even worse numbers.
I know numbers are not the only thing that needs to be considered I’ll be the first to say that, but sometimes things are just too obvious. If a hero has one of the worst win rates why are you nerfing them? same with Genji, if his numbers are great, why are you buffing him? Tbh these changes seem more like they catered to people complaining than to actual balance of the game, and I suspect they will regret it when the waves of Genji threads start coming.
