Its hard to call them san'layn options tho.
To be fair its one single option and its called dark ranger. Hell they could have atleast called it darkfallen to suit both organisations. Its just weird. I wish we had more vampiric options, such as fangs, claws like those blood princes.
I have noticed some heavy resistance in the alliance, but also horde as they are just mere costumization options, people wanted the full thing.. the whole its your own interpetation and how you want them to be.. is actually hitting a lot of nerves. I knew this would happen, which such a vague explanation and you as player npt actually playing an undead or darkfallen, just a blood elf with pale skin.
Its lazy imo.
