She's still very good at taking space and is probably better at getting kills while doing it than Jett or raze with the slides buffs. The wall change is more of a side change than a nerf and helps with her teammates scaling (depending on how it's used). I would have liked some different changes to her stun tho, removing one kinda hurts
For defense I assume she would just be the rotator since she has a lot more run and can move fast. She's definitely not a defense agent tho
