@DankTolietThey've made her easier to shoot on it but she's always been strong due to the combination of her abilities. If you watch any pro or top level play solo or no fill in the past they always used her because her movement is better than every other legend. Her passive means she can constantly slide around and do movements no other legend can. Couple that with a free vertical ability and she can escape better than anyone. In a team her q means she can raise her whole team to height and you can't shoot 3 people at the same time. And that gets even worse if she dumps her ult on you and they throw nades.
Path has good movement but his hitbox is gigantic and his grapple isn't a one click ability. And he doesn't have a real passive Valk moves so slow on her jets she's about as easy to shoot as there is and again no real tactical as her rockets arent very good against players that are good. Vantage bat gives her away and needs to be planned. Plus she has no real passive. Octanes passive heal is ok but not really that great. Only rev compares right now but thats because his extra health and recovery on knocks, not necessarily do to movement.
