Learning to play Dominion without having to resort to the common OP champions.
By that I mean champions like Jax, Jayce, Diana, Yorick, Kass, etc.
I consider champions like Wukong and Poppy to be powerful, rather than OP.
Pretty much, I want to become good at Dominion without using broken champions. Using powerful champions is okay, there is nothing wrong with using strong champions. What wrong is spamming broken champions like Kass/Teemo that you know pisses people off when you use them to get easy wins.
