At first it looked like Blizzard was paying attention to the server situation and what the community was saying:
but they closed down the free transfer to Alliance long before Sulfuras even had a chance to become a balanced server. I think when I was scanning the concurrent online players around the time they closed off transfers again, it was about 65/35 in favor of the Horde.
Just another example of Blizzard doing an awful job at managing server population and balance. If they had just allowed it to come up to 50/50 balance, it would have had a chance to become the next Grobbulus.
I had some friends on Sulfuras Alliance. They all transfered to Atiesh, gg.
