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.)
Space in this game is a complex concept. I don’t blame people who think tanks are just supposed to stay in the objective or to be a meat shield. It’s way easier to understand a support or a dps job in this game than the tank job.
For example people will flame me for keeping 2 supports and a dps busy in a back line because they can’t understand the space is being created with that kind of play and the value that it brings to the team fight
