I'll be sure to silently creep on lone Ana's with my floaty legs. hahaha i kid.I do this a lot and I make sure to keep an ear on flank routes near me so I could hear flankers coming.
Anyway ya it's all just rules of thumb and what not. You can basically just no scope like Rein every range since they're large and slow with shield up. You can no scope Winston for the most part if you can land air shots unless they're AD spamming pretty far away. I personally dislike how hard it is to see Ana's projectile though. Makes it harder to get feedback and compensate your next shot haha. Aim for 70/70+ acc as long as you aren't farming and should be fine in general. Don't worry if acc drops when people keep diving you and you're forced to fight them more often, it happens. Just show them Ana's boss and make them regret cos Ana just wins 1v1 lol.
Hm does the projectile actually help you not fat aim your tanks? Don't really know but that's interesting. Also ahahaha yes when random things block your heals :C Worse still if they block your grenade after you tried to jump shot it over their head but they jump or walk into you ;o;With Ana I think hipfire is okay if you're just sort of spamming healing into a cluster and it's not mid battle. The issue with scope healing is the hitbox is so large that often you cannot get around targets like hog or Dva (just get out of the way fuuuu).
But scope healing is my preferred way to heal, and getting quick scopes down helps you a lot of the time with targets like Phara and Genji.
My two cents.
