I recall there were plans to add in a post on the Community Council forums regarding playable race requests. A thread has been made by someone on there, seen here:
You can give a like to the post despite not being on the Community Council if you’d like to show support. If anyone can spread the post around, that would be appreciated so we can give it support.
Edit: A list of the race request megathreads have been given to them within the Furbolg megathread. We should be seeing others added to the post in the near future, including my Stonemaul Ogre post I mentioned.
I’m very happy to see race request megathreads getting a voice on the Community Council. No guarantees we’ll see all our dreams come true, but it does help our chances, in my opinion!
