Reasons why Vayne is (arguably) too powerful now and does not have a weak early game

And this doesn't have to do that much with the tank meta. Being a "tank meta" was just one of the things that naturally favored her since she is supposed to be strong against tanks. But champions like Kog'Maw and Tristana are also good against tanks, yet they are not nearly as powerful and as popular. No, the tank meta isn't the main reason why is too powerful now. The actual reasons are:

1. Every early game ADC and support was nerfed. were all ADCs that have a very good early and/or mid game, and they were all nerfed. They could outbully and be stronger than Vayne during those stages of game and end it before Vayne could reach the late game. Supports that could poke and harass Vayne out of lane during the early game, such as , were nerfed too.
2. ADCs that could scale just as well as Vayne into late game, such as , were nerfed too. Therefore, Vayne has little competition. Even if she is not the most powerful ADC by late game (in terms of damage), she is the most powerful late game ADC (there is a difference) because she is the one who has the least weakness throughout the game. Her ability to self-peel makes her far safer than all other late game ADCs except Tristana, but Tristana does not have nearly as much damage as Vayne and has a way worse early/mid game.
3. Riot, buffed . They buffed the on-hit % damage, they made it so that this on-hit damage now benefits from lifesteal, and they increased the range from this item's active. Since Blade of the Ruined King is Vayne's supreme core item, every buff to this item is a buff for Vayne.
4. Almost every other ADC no longer rushes lifesteal items. Remember the time where ADCs used to rush ? Now every ADC rushes instead. The problem with this is that on the longer run, Vayne will outsustain other ADCs during the early/mid game because she can afford to build early lifesteal items without it hurting her damage due to her Silver Bolts and the AD steroid on her ult. She also doesn't need Infinity Edge to out-trade other ADCs, even if they have Infinity Edge themselves.
5. Riot nerfed and , which are the only defensive items with potential to reduce Vayne's overall damage. Attack speed reduction is the only actual counterplay to her Silver Bolts, as you can't counter with armor as it is true damage, but you can't counter it with HP because it is based on maximum health. But since it is an on-hit effect, you can counter it by reducing her attack speed, since you will reduce how often it procs. But as I said, Riot nerfed the only two attack speed reduction items that we have. Not only that, Riot removed attack speed reduction from a number of champions, that includes and .

Due to all those changes, Vayne is now a monster. We can't say that she has a strong early game; but she is no longer as weak as people say that she is. Yet, she scales so damn well into mid/late game. This needs to be adressed. It is safe to say that Vayne needs nerfs. Either that, or buff every other late game ADC so that they can compete with Vayne, and/or buff the early game ADCs so that they can actually outbully Vayne, and/or add more attack speed reduction items/abilities so that we have better ways to deal with Vayne.
