I see a lot of people think tank is just a big damage and cd sponge, but that isn’t true at all. I don’t know where this misconception of the role comes from, but I really wish it wasn’t so believed in.

Tanks are aggressive space takers. They don’t sit around, hold your hand, and take all the enemy’s crap for you. They push in, kill things, force engagements and cooldowns, and allow their team to push forwards. Reinhard’s shield for example isn’t for his team to stand behind so they can be safe from damage, it’s for Rein to use for himself to push up without taking too much damage. To play tank effectively you have to use your resources selfishly (for the most part.)
