Tank meta not dead. Tanks are op

As of the moment the ''tank meta'' is still alive and very very well off. There are MORE than enough items out there to counter tank build. With that in mind i am going to list my opinion and experience on this current meta. In most of the games i play there will be anywhere from 1 upwards to 3 tanks. over 3k hp on all of them and over 200 MR and Armor on them. So you build pen items obviously, but that;s not always easy to do. Most people would say just kite them but that is far easier said than done. I have seen tanks with upwards of 250 ad ((referring to ad tanks as the problem not ap)) with often just 1 or 2 ad items. Most of the time this will include , as well as a the only thing that urks me is the fact that if you have 2 or more of these tanks, even supports in some cases, the chances of you wining will just drop heavily. Again a good thing to try is just pick them off, and you aren't wrong but even with that once they realize what is happening they will just group and power push any lanes. Your team will do moderate to no damage at all to these tanks unless you focus them with more than a single person. Im fine with tanks being strong and powerful but i am not okay with the fact that with just 2 damage items of ANY type they can not only tank for there team but deal ''carry'' amounts of damage. I honestly think that the ad/tank items that are out currently need a Nerf to the amount of ad that is given. So that way tanks can tank but you don't have to fear them as much as you do now. If someone is fed yes something like this can happen with ease and they will just destroy obviously. But picture what i say on a playing field where everyone is even in level and gold. On both sides of the field both opposing and friendly i just don't like how powerful and game changing this can be. Most of the games i have played it comes down to who has more tank than the other. Game are less so focused around skill rather than raw power when it comes to more than 1 or 2 tanks. This is just my own opinion however and i would like to see other peoples opinion on this and if you could change something what would it be?
