For me, I do snap shots when I can. Like, in some ways, you gotta be quick, because when the enemy team sees you, (especially the D.Va), you’re gonna wanna make sure they don’t live long enough to get close to you. But also, if they’re distracted, I like to track my target. Just keep practicing with her, I’m sure you’ll get the hang of it. (I’m not exactly TOP ranked, but I’m pretty damn good with her imo. I Main her. I still have a lot of work to do). Also, just try to relax and be aware of surroundings. Constantly make sure that no one is trying to sneak up on you bc when you’re scoped in, it’s easy for a Tracer or a Reaper to flank and get the jump on you. That’s just my advice. I’m sure you’ll become a great widow player!
