I miss tanks being as popular a role as mages, or marksmen, or assassins. I miss being able to take Nautilus into the jungle, and use a cheesy Q-Max Zac in the toplane. I miss Malphite and Amumu ults being the deciding plays in games. I miss big team fights with tanks at the frontline, surviving until the end of the fight.
Tanks playrate have plummeted over the years. They feel less useful and more like niche picks, Malphite and Rammus being the most useful since they just can stack armor. The tank-rework only seemed to hurt some fun champs like Zac.
I know this sounds whiney, it's just they are my favorite champions/playstyle/role to play, and it feels like that role barely exists anymore.
