Tanks
Are you tank? Do you suffer from auto attacks hitting you? NO PROBLEM! Use your built in ability to slow their auto attacks! OR buy a frozen heart to slow their attacks more (and perfectly give you everything else you need too).
But you are slow you say? NOT A PROBLEM. Buy even more armor that makes you move around really fast AND THEN deal more damage while being harder to kill!
What that you say? You don't do enough damage? NONSENSE, enjoy abilities that scale off of HP and armor or keep farming until you can 1 shot anyone or have absurd amounts of health and armor.
...
Are you a fighter? Do you rely on auto attacks? NOT A PROB....um, oh wait, sorry you are screwed. I would say get some tenacity but Riot effective removed that stat.
...
Seriously.
