Tanks need/bruisers to be nerfed or all Assassins need a buff and also amor pen items

These days im seeing tanks in every lane and every role, they even ran Assassins from mid lane, being honest, how many of you can say that when u play a game of league the other team has at least 3 tanks? I remember in the past where people would say as long as u dont feed the Assassin then the game would go even. But now a fed tank.bruiser wins u the game because they soak up all your damage and probly do more damage than an adc and mid Assassin combined. All that damage when their only offensive item is how does this even work. for example I have seen played perfectly in every lane. no matter your build cannot die but kills u in an instant. In the past if an Assassin unleashed their full combo + Ult on a tank then about half their life is gone, which is understandable and fair cause its a tank. Also if the tanks unleashed their full combo the same would happen to the Assassin because the tank has no offense. But today if an Assassin with full build like has + + + + + (bear in mind no defense but a lot of offense/damage) if talon has this build and a has + + + + + (bear in mind little/no offense/ad but a lot of defense). If unleashes his combo + ult then vollybear looses 1/4 of his life(maybe less). Which is kinda acceptable(he should loose more) but none the less i'll accept that. But the funny thing is that if unleashes his combo + Ult then is dead. Thats the part that buggs me. Talon and vollybear is just 1 example, but in general tanks/bruisers seem to do more damage than an adc. Just look at and late game they can 1 v 2 your 2 bot laners. and are the only 2 tanks that seem balanced and sensible. Actually more because if you see him win a 1 v 3 or a 1 v 4 you know for a fact that its because he has 300+ stacks, so when you get killed from him you know why but all the others kill you before they even reach level 6 whereas Nasus have to bet at level 6 with 150+ stacks to be a threat. Not saying he needs a buff or nerf cause he's perfect as is and when he kills me and I look at his build and stacks im cool with it. But those other tanks are way off balanced. RIOT doesn't have to nerf them just bring back armor pen items and make those items actually penetrate armor instead of hitting me a 6 for a 9. And P.S and don't do piss shitt against a tank even in the hand of
