I don’t like the idea of a leap year dragon getting an evolved form because it deviates from the other leap year dragons, but equally I don’t like the design of the dragon to begin with because it breaks the pattern as well. It’s essentially just the Mesmer dragon all over again. Really I think they should just slightly redesign/recolour it rather than give it an evolved form as that doesn’t really change anything. If DECA recoloured is to be white, black and gold, possibly with elements of blue, it would likely be more popular.
It’s like DECA just decided to give the next four headed dragon that they designed the title of quadruple leap year. Personally I think the quamera dragon would make a better quadruple leap year dragon.
