Theres rarely a 1v1 situation since everyone is huddled around an objective or pushing to it
genji has insane mobility. he can get to the back line and pick off one or two people and still mange to get out. there are routes on some maps that allow you to get to the backline or flank really quickly, if there's a video out there i suggest looking it up.
This. A good genji is obnoxious. Sneak around the back, harass a few people, then sneak out before you die
I had a hilarious potg as d.va. was on offense and hiding near the point, because a few people saw me and I was trying to heal up. They both came around the corner together, so I boosted and knocked them off the map.
Seriously, knocking someone of the map is the most satisfying way too kill someone.
