Typical LOL community...
You complained that tanks are too strong, you spammed the "ADC 2k17 LUL" meme over and over and over. I posted many times that tank meta is best for the game balance, the biggest % of champions is viable in a tank meta, games last longer and are more fun, snowballing isnt as strong, almost every class has its place.
But no, I got downvoted into hell every fucking time. Now you complain that tanks are shit and ADCs are too strong. Well no wonder, you asked for this meta. I dont know how many times we need to go through this cycle before we learn that tank meta is the lesser evil. Hell last time I really thought the gameplay was perfect was mid season 5 and that was a super ultra tank meta, I remember that almost everything was viable.
And 2 years later the shit is just getting worse, look at this meta -

who blow everyone while having infinite mobility,
the unstoppable tanks,
the only decent mages left in this game,
absolutely blowing everyone up in matter of seconds from a mile away,
breaking the meta, shield champions saving people from 1 shotting become gamebreaking especially with their shield supp items
. Assassins are trash (I hate them but no class should be unviable), every other tank besides the 2 mentioned above is pure trash, tank items are absolute shit and they are forced to go support style with
, non-crit ADCs like
are trash, at least 50% of jungler are just not viable AT ALL, bruisers are very very weak, most mages suck or were nerfed so they now suck as well, games last 25 minutes and are decided after 5 deaths, genius RITO puts in the fucking herald to make the game even faster
. From 5 class updates at least 3 were complete failures, juggernaut pure trash; ADC was decent; mage was trash and made many mages shitty, also removed the mana management from champions with a fuckton of mana/mana regen; assassin update looked good at first, but the items were broken, lethality broke both assassins and adcs, now its nerfed and AD assassins are immediately shit, AP assassis got nothing, Kata is the saving grace, LB is still cancer and will get reworked yet again; tank update is perhaps the worst of them all, totally random reworks, Sejuani made even worse, Zac made into most broken thing in the game, Maokai turned into cheese champ, tank items turned to be EVEN worse when you think it wasnt possible, now you literally cant build tank and expect to win.
Every single shit to catter to people playing squishy champs who want to go glass cannon and blow everyone up and finish the game in 20 minutes because that is fun right??? No, its not. But whatever, I guess most players are fucking casuals and they also pay the most since they probably have jobs since they dont play a lot...
