I wasn't sure if I should post this in this section or Exploration.... Mods please move it it doesn't belong here.. Thank you.
Before you read this I just want to say this is just a little bug I found. I don't believe there are any advantages you can gain.. I was bored looking for Gondria for my Hunter when this happened....
Ok so this bug is with the Gundrak Bat Riders in Zul'Drak .. When you fly right next or on top of them them they will fall to the ground.. When they are on the ground fly down and aggro them.. You can then fly back up and they will swim through the air to attack you.. Looks pretty funny.. The will chase and attack you as any other mob does just in the air..
