So let me see if I understand Xayah and Rakan

Rakan, a joyful battle-dancer, friend of both vastaya and human since he threw parties with both , falls in love with the first girl that doesn't fall for him (cliché much?). She, seeing that he is quite useful, uses him in her quest for vengeance against humans because she was once almost robbed therefore she concludes that every human is a dick (falacious generalisation much?). Hmm...

She is racist with both humans and yordles and then yells for freedom and says that magic belongs to the vastaya (and here I thought magic belonged to everyone like air or water?).

She sees fellow vastaya that are friends with humans like Ahri and Wukong as traitors just because they don't support her cause.
