Season 6 Champion Problems

As the preseason progresses, I am seeing so many champions that are played over and over against that wreak my team, it is kinda annoying. I have seen so many people play Jax, Zed, Gnar, and Vayne that it gets super annoying. Keep in mind that I play normal rounds, not draft. Season 6 is so based off of pure damage/tanks, that the AP people and mages aren't very effective. It feels terrible when a Yasuo that sucks at playing him gets super fed and cannot stop killing your team. It isn't right that people are favoring the AD assassins just because Rito is favoring them WAY too much. With the new item for them, and it being based off of pure strength, it isn't fun to play against a regar that can 1 shot your ADC. After playing a ton of games, I have seen a Yasuo pentakill 3 times in one match, and it was ridiculous. It just isn't fun to play a TF against a fizz that has a Jax camping you in mid. It isn't fun, and after awhile I just want to blow up and take an Advil. People are so toxic these days that it isn't even fun to talk with your own team for a strategy when they are on tilt. Riot just please make the mages go back, because it just isn't fun to face a snowballing irlelia, Yasuo, and zed, with a unkillable Mundo. Please just tweak the whole concept of the AD dominated meta. I can't play TF anymore because every other game I get a fizz/Jax jungle that gets so snowballed it isn't worth trying anymore, or a Yasuo mid with a zed top and an flaming/afk person on my team.
