By the time next Blizzcon hits, this thread is gonna hit, or nearing 10k replies.
The people have spoken Blizzard, worgen customizations is so bare bones and boring compared to the other core races and what they received this expansion.
We want a OPTIONAL tail, so if you don’t want a tail, you can have it off. 
We want actual hair styles much like the alpha worgen models that got scrapped just before Cataclysm released.
We want straight back male worgens.
We want a option to have the normal worgen voice much like Celest the Harvester.
There’s so much a lot of us have requested, even a dedicated thread that goes more in to detail on all the stuff the worgens, and wow community in general wants for worgens.
If we’re lucky, they will see the huge backlash from their comment during Blizzconlie and actually push to have more customizations as early as 9.1.5.
Only time will tell. I will say thought that out of all the different request threads outside of the blood elf ones, the tail thread has had a lot of support from so many people in the community from Alliance to even our friends in the Horde.
Here’s hoping we will get tails by the end of the expansion, and if not, as early as the next expansion!
