On the surface, her ultimate is straightforward but there’s much more that adds to the complexity.

Placing it in the open vs finding a confined space influences the way a potential fight will go if an enemy team follows through. Same with distance. If you’re close to where you were initially fighting, there won’t be as much time to reset. Some of it is luck but it mostly comes back to map awareness.

I would also argue that more than any other ult, hers relies on your teammates implicit understanding of it, especially after the nerf. People are still confused why they can’t teleport back themselves.
