You do realize that it is going to be virtually impossible for you to have an individually distinct character in an online game, right?
Someone else is always going to pick the same class. Pick the same talents. Even pick the same transmog/cosmetic outfit. Back in Vanilla, we had a joke about how we had 3 troll priests in our raid group that looked completely identical - wearing the same tier gear, same talent spec and even the same face, same hairstyle, same hair color. Note that this was before the Barber shop was added.
