Why is Vayne the way she is/ needs a nerf?/ poll

To start it off, the whole point of this article is to question why she has not been nerfed yet. I have just played four different games in a row and all of them have been defeats solely because they had Vayne as their ADC. Two of these games, she didn't get fed at the beginning but still would unreasonably quickly take any of our team out with minimal effort. Now I shall list my complaints:

1. ( and my top complanaint) Since pink wards have been replaced, Vayne can not be shown with control wards anymore. So these "good" Vaynes dance around our team with no effort and we are unable to see her no matter what we use.

2. Her Q half-healths most of our team even though its cooldown is extremely low and gives her a small flash type of roll. (not to mention this ability isn't an ultimate)

3. Vayne's passive allows her to chase people down which enables her to prock her passive even easier than normal.

4. With her kit, Vayne doesn't have too much potential of escape except for the fact that for some reason she has an immense knockback that will stun champs when knocked into a structure. For example, our somewhat counter for Vayne in this one situation was our top lane Jax. As he jumps to E her- and remember she can't hit him right now- she can still use her E on him ( EVEN THOUGH THIS IS STILL A BOLT FROM HER CROSSBOWS) and knock him back and then kill him easily since she has the ability to chase with her passive.

5. Why in the world does her ultimate allow her to go invisible? It already gives her immense AD to critical strike people even more than she already does.

   To start off on my solutions section of this article, I have 3 ways to nerf her down to a more balanced level.

6. Change her passive to something that doesn't allow her to kite considering her kit already allows her to dish out so much unreasonable damage.

7. Lower the AD ratio on her Q to stop her from half-healthing with a crit, or just make the cooldown significantly longer.

8. Either remove the invisibility on her ultimate, take off the extra damage it gives her to use, make it so you can see her if she gets too close, or make it so control wards can see her now.

   And yes, I know this rant may not solve much, and I know everyone has their own opinion towards these matters, but this is League of Legends with such a diverse group of players and skill groups that I don't see why champions get changed just for the intent of the high-elo players to play one single champion. Us near the bottom of the ladder are getting crushed by these champs that Riot insists need to be buffed even more. Remember, our teams don't build to win every single time, they build to play the champs they want to play and have fun with but then you have these types of players like Vayne whom play these unreasonably broken champs to ruin these games for the other people. The last game we played, this Vayne had Nautilus, Nasus, Orianna, and Ivern to protect her from all of our assassin type of characters so there was no point of killing her unless she wandered off. Then, she bought a guardians angel ( which also I have a problem with, it allows these extremely powerful champs a second life to kill with, so as the assassins jump in to kill the carry, they just get revived and nothing happened except one teammate dying) and we were unable to take her out at all with these teammates making a "vayne comp," if you will. ~this is the one and only CabbageSalesman, I am tired of this vayne, there are over 120 champions and I have a 3/5 chance to ban her to stop us from auto losing these games, and with this assassin update it's now even worse. Have fun kids, good luck.
