Regarding the recent "Ask Riot" and Vayne

> Finally, we also want to reduce the early game power of marksmen who are strong late game by a bit. Some of that’s reflection of their late game strength, which should come with a trade off of early game weakness. Some of it’s also to help other champs lane against them, whether in bot lane or elsewhere on the map.

Vayne is already in the gutter early game right now. Additional nerfs to her on top of the previous nerfs which took away her attack speed scaling and attack damage from Patch 8.2 would destroy her into unviability.
