Riot, you make champs with really cool themes and personality

Yet their kits don't really fit them that well. Kalista, a spirit of vengeance you can give your soul to to get revenge on someone. That's awesome but her kit just doesn't really fit with that except her ult and arguably her Q. Ekko, a young boy who invented a time machine he can wear on his wrist. His kit fits better then Kalista's but it is simply overloaded. His ult fits his theme perfectly and his W also fits. Braum I feel is a really good example of theme and gameplay mixing. He is a hulking protector of all and that is what his kits does. I know you can't make every skill perfectly fit the champs theme but more then one ability should fit their theme perfectly. It could even be their passive as one of the abilities that fits perfectly them such as Thresh's passive.
