Average human response time including pro gamers is around .25 and so she has .65 to hack.
You basically have .4 to react to hack. Getting behind a wall with her .2 los loss means you really have .2 seconds to get behind some barrier to actually break the hack.
Or .4 to turn, spot her, and actually hit her. Even harder todo if you’re playing a projectile hero or Rein.
Even for a pro, that’ll be hard as hell to do.
