I just need to throw in here that it can't happen right now. Treewyrm has agreed that in the future, it's possible, but not right now.
Too much lore and work has gone into the K'Hara's mythos for 4.85. Another Nomad faction popping up right now just can't happen. Some rights are reserved for those who take the time to do something. You can't throw a monkey wrench into that.
It's a possibility. Not right now. In the future. That's fine.
EDIT: And now I'll try to back out of this. Everything has been said, and agreed on. If I post again, Zelot will probably give me spanking or summut.
