VERY small leak of the Vladimir Rework
https://youtu.be/vgkjyVooGNg?t=11
It's just a small clip from the video showing off the Classes and Subclasses, but you can see Vlad use an ability with obviously updated textures that doesn't appear like anything in his kit. Also, his Q in the League website has that glitched teal icon. Just a theory that his Q is being replaced, but you can clearly see that is an ability we haven't seen yet.
EDIT: Confirmed to be his new E, not his Q. https://cdn.discordapp.com/attachments/139883261458513920/171718464011108354/unknown.png
