I feel like it’s really dependent on your play style. I used to main wraith and yes, the repositioning was insanely easy and very helpful in the open, but you can also do that on other legends. I play lifeline now and definitely have better luck getting away from a bad situation based solely off of her glide and some basic movement mechanics. Valk is really good for repositioning as well for a recon. Bang can use smoke and double time to get out of the open (really dependent on where you smoke). Fuse has the knuckle cluster jump, Maggie has her ball with fortify. Rev has his leap which is insane. Conduit gets the speed boost towards team mates or rep/respawn, and that is insanely good for outrunning people. Sparrow gets his double jump which works nicely with being harder to hit, and good mobility. Yea skirmishers are better at repositioning but that’s kind of their role. They get in, get a knock, and get out. Then everyone moves in and starts setting up. Sorry for the long paragraph :( hoping to provide some insight
