Mayhaps we've created our own monsters.
By studying skin purchases, Riot has decided that adding champions who are fun to play as - despite being at the expense of 9 other people - is the way to go as everyone that plays them frequently will have such a massive ego that they will buy their skins. Thus Yasuo, Darius, etc. were born.
Maybe us complaining about Yasuo is really just us complaining about ourselves and our own spending habits. Have we inadvertently created these demons...?
