Well he intended to go to veigar stun so basically it works

As far as im concerned there are only 2 scenarios this W is possible: 1. Fiora hitboxes are slighty larger while using W enabling cc proc from cage 2. This is inhuman timing unsing W between walking into cage and geting cced and thats only possible thanks to TPS like in minecraft where you could do ""1 tick farms" that also worked on kinda same basis

actually 3 forgot about possible input to usage delay but that would be as hard to pull of as 2nd possibility
