Again its your own interpetation, no matter what your opinion is. Forsaken paladins still isnt really playable. I mean your character is a clear example of your own interpetation m8, idk what else i need to tell you, besides hover over your character and see your still a blood elf. If you want to rp as a vampire, you can or a dark ranger who took up a blade for all I care, doesnt mean its canon.
Its an rp element as you figured out by yourself in your first first response. See high elves, same thing.
