What is the purpose of a tank?
Ok. A tank, by traditional means, is supposed to be a person who sacrifices damage output to be more disruptive and can take a hit so the damage can do their job. Right now a tank can take on any damage dealer in the game, under tower, kill them, then walk away. So I am trying to figure out the trade off, the sacrifice a tank makes to be tanky. It doesn't seem as though that trade off is there, so that means that tanks do the job of the damage dealers just as well, if not better. so what is the point of a adc or mage if a tank can do everything they can ( other than attack at a range, but then again most tanks have gap closers) better?
