Seems like WoW are going to be getting some nice zandalari invasions in 5.2!
"Zandalari mobs will spawn in Pandaria zones, that will take small groups to defeat. They have a chance to drop crafting materials, reputation gains, an achievement, and even the chance to get one of three new rare mounts!"
Some nice rewards too!
