Expert take
Zeri is a very strong pick when you understand that her identity is not “I move fast,” but “I make the fight impossible to close cleanly.” She rewards players who can think two seconds ahead: where the next wall will be, which crowd control must be waited out, and which target can be hit without losing the exit. She is not the best choice if you want to crush lane purely through range or burst, but she becomes frightening when your team can create a long fight around an objective. Played well, she turns a protective draft into a clean-up machine; played badly, she wastes E, walks too close and dies before her scaling has real value.
