So, A buddy and I were bored on a PvP server and were flying around ganking people, when a druid (non-epic flight form) flies by us. My friend (being an elemental shaman) decides it would be funny to use his thunderstorm on the druid.
He catches the druid (both are still in flight). My friend dismounts in mid air and thunderstorms. The druid is knocked back and his flying form changed into his Night Elf form. He falls to his death.
We have tried this on other chars, Apparently:
When you use thunderstorm on people who are flying around they are dismounted and will fall to their deaths!
This makes for so much PvP fun causing them durability damage!
Enjoy!
