Look , when something gets gets changed in the game and a champion ' s spell what was previously balanced becomes way stronger than before nerfing it is reasonable . Just imagine what was happaned if in the new patch comes an item that gives 2 second of invulnerability if you heal someone with a single target healing spell . Do you think soraka ' s w still balanced because it was balanced before ? 1 second invis multiple times in a teamfight isntantly on demand is too strong now that theres really no counterplay for it . You cant reveal a stealthed unit so its basically untargetability or better because you are not visible so you can move to a better position . It deserves a nerf . About the q ratio nerf . vayne should be about killing tanks and duelling , not oneshotting squishies . Lowering her q damage nerfs exactly this part and this is the good direction .
