Here's a brief overview of the preseason's state

Any ADC top. Corki, Quinn, Ezreal, or Kog'Maw mid. Graves or Kindred jungle, although the former, the one not designed to be a jungler, is much better. ADC bot lane, and Thresh or Tahm Kench with them.

So much diversity! Almost every class is equal and viable, and none of them totally ass fuck every other class.

You know, not like Riot's buffing the strongest role in the game while also nerfing literally every other role. Not like that at all...
