It’s usually the other DPS that is enabling Genji. I just literally had a match that Genji was getting non-stop nano blades. I switched to Pharah and with my Mercy player dove their Sojourn and Ana… That Genji had nothing left. Went in 1v5 dash, got killed. We realized the only reason he was good because his Sojourn was doing a lot of damage that he was capitalizing on.
This is Plat 1/Diamond 5 games btw. If you play any higher than that… idk about that experience.
