The best way to acquire a Shadowmane is to transfer to any popular server, and say that your a Beach Bob who needs a starter tame. More than likely, an advanced player will gift you a Shadowmane that’s better than any wild one you could have tamed. Transfer back to your original server, and enjoy you new flying murder kitten. Might take a few tries to find a generous player, but if you bug them long enough they will usually yeild.
