Tanks are Tanks

I dont't understand people want to increase damage on tanks to be on par with ADCs or higher.

Tanks are defined as tanks because they can absorb large amounts of damage for the rest of their squishy team. However, the way the game is designed right now, every tank is essentially a high damage meat shield. They deal large amounts of damage, and take little.

Tanks should focus less on dealing damage(leave that to the carries), and more on taking the hit for their team and laying down the CC disruption.

Now you might say this will kill the popularity of tanks, but I'm not asking for extreme nerfs to the damages of tanks. Their damages should just be toned down a tad bit to be lower than the damage of the carry roles.
