The color, characteristics or gender of the champions have absolutely no effect on the outcome of the game. Most popular games, literature, movies, and anything else with an audience will use visuals that the latter can relate to. Games like League Of Legends is a program with set mathematical instructions. They don't need to have humanoids, monsters or creatures of any type as a visual in order for the game to be played through. It could be multiple dots of different colors or shapes with set programmed skills. Racism and bigotry has no business in here.
