Tank meta...... help

So, yea..... Tank meta isn't going anywhere apparently. Can someone please help me figure out how we can beat them? How is this balanced? In this game we got so far ahead. The enemy team didn't get a single tower till 37 minutes in. All they did was sit under the tower and cleared the wave.

Supports feel it the most. I was the thresh.... what am I suppose to do? Hook and flay them out of their tower. Then what? The tanks just walk right back under tower. My ADC tried to build accordingly, got BORK and Dominik's Regard which did nothing. We were ahead at all point in the game in objectives and kills, yet the tanks win. I don't mind having tanks in the game, they bring more strategic elements to the game. But they are just too powerful..... And I know the argument is gonna come up.... "Then just play tanks". Why do I have to play something I don't want to just because Riot can't balance its game.
