Messing around with some mates and some goblin gliders we managed to go into a spiral of doom with our gliders by following each other in a circle after a short amount of time the gliders start to turn so fast following each other you all get a DC.
1. Go onto a high point in the game we used tall mountain in Kun Lai
2. Jump off one after the other with Goblin Glider we tried with 3 people
3. Once all in the air everyone should follow the person in front and the first person to jump off should then follow the last person to jump off
4. Now you will start following each other in a deadly spin getting faster and faster and eventually all DC
Just something if your bored would be fun to see what happends with more people in the train.
