Nerf Vayne, Buff Demacian Boi
Why are you buffing her though this upcoming patch, shes already overpowered despite the nerfs a few patches ago. Its pointless to fight a fed Vayne unless you have somebody that can stunlock her. Going tank is pointless because of her percentage health damage (which also applies to every champion in game)
heres one of my experience A fed Vayne (2 items) tower dived my Xayah alone and succesfully killed her with half of her health remaining, I decided to engage since I'm Pyke with a full health and I still got killed in 5 shots. I got so tilted after that and said in all "damn these meta slaves" then proceeded to get killed again in the jungle :) The only time we succesfully killed her was when I stun locked her with sylas (which was very effective)
