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.
