she is definitely a flanker hero. she is a shorter ranged squishy hero that aims to control space whether that may be claimining enemy territory, reinforcing current areas or to go out and getting picks.
For a shorter ranged squishy hero to function, they will need to prescribe to a “get in get out” gameplay (i.e. a flanker). ESPECIALLY when it comes to claiming enemy space. Like she’s no rein or orisa who have high sustain to walk up and threaten space to grab it. nor is she a sniper to be able to threaten long sightlines with range. She has to go sneaking around with her lower range to claim it. If that doesn’t sound like a flanker, idk what does. Heck even her comic shows sym flanking to get what she wants.
