What is happening here in Shadowmoon?

[Vexae]

So I went to the Alter of Sha'tar to find extreme lag and this Night Elf Hunter, Datangli, was doing something with these Dragonmaw Skybreakers. There are A LOT of them! As soon as I got closer to find out what the hell was going on they took off, but I was able to snag some screenshots.
Whhaaaaaaa?
