Zed or Zed?

So I was just thinking about that champion. I don't play mid so much, but I play ADC a lot. I can see from game to game Zed picks in enemy team and this is how it goes. No matter what champion you pick (mage or assassin), I always see the same thing: Zed poking with W-Q combo untill guy is around 20% of his HP and then just dives or goes into our base and kills our mid laner. So you can go back every single minute and be useless as shit or you can stay there, feed zed and be useless as shit too. In my opinion, it's the same shit. So I bought QSS, but guess what, he doesn't need his damn ult. He just W to me Q-E maybe 2-3 AAs, that stupid item procs and bam, I'm dead. So I think we should just start a new meta with bruisers and tanks on mid or something like that.
