I recently discovered that horde have a nice relaxation area with a golf course and a swimming pool jump enabled with elevator up to the platform.

They can go there have a nice relaxation day and the go to raids/bg in a good mood. There is nothing similar for Alliance. Year of battles with no relaxation for Alliance.
It is clear now that Bliz is favoring the horde because most of their dev are horde. GG Bliz
