New elements masters

we already have a master for wind and for earth but when will we have a master for dark, light, water, fire. like a real master not fire champ like brand and my idea to do like you did with rakan and xayah get two new champs in the same time and they could be brothers like light and dark every one took a way of there father and mother and the story should be like an angel love a demon adn got those cildren that had a human what looks like a human body with the power of dark and light it will be really intersting ihope everybody support this idea. thanks for reading.

editing: because many started talking about dark magic we are not talking about magic we are talking about darkness and lightness not a kind of magic and about that we get a new due champions is not really a abd idea because many started playing the due cahmpions in bot and everybody love how they have so many mechanics togather and lol started making a big diffrence in cahmpions lore and abilites and i think change and making new ideas and much more mechanics would just make the game even better and i dont think all champions should have 4 abilites and 1 passive thats is not important but every champ should be in the same skill level and power as others and that doesnt stand by the number but the skill needed for the champ and the power but we need to get b to the topic about a new due is a great idea and bringing the world of demons and angels to the world of lol would be amazing
