Anyone Else Feel Like Tank Meta=ADC Meta?

It seems to me we only end up with tank meta when ADCs are super safe because of support peel/heals/shields. Which then requires you to CC the enemy AD for several seconds for your own AD to DPS them down, and tanks are the only ones who can survive that long. Since even one shield late game pretty much stops any but juggernauts (who are usually peeled pretty easy) and carries from doing meaningful damage, there's no reason to pick bruisers or fighters unless you're just splitting all game.
