I’m for this for two reasons…
One: you can’t have non evokers use their racials in visage form and then turn around and say evokers must change because to preserve their dragon identity.
Like that’s a double standard…
How you gonna tell me a drac warrior can unfurl their wings while in visage form but an evoker can’t???
And if they can do that for their racials they should be able to do it for all draconic abilities…
If anything it makes sense for the class that emphasis on draconic combat to be able to master it in visage form and for the non evokers to be forced into dragon form.
Two: this would make it possible for all races to be evokers.
