Hello everyone! I've been lurking the forums for a while and felt it's time to contribute in some sort of way. I searched the forums for Dancing Flame and 2-seater flyer and found nothing similar to this so I feel it's safe to post.
If you have the Dancing Flame vanity item, and a Transformation Mount (such as the Sandstone Drake and RAF Obsidian Nightwing) you can create a server side visual bug of you riding yourself as your shapeshifted self...if that makes any sense. This is only server side. I was trying it myself with some friends in the group, and they told me what happened. I personally could not see it myself on the clients side, so I had my friends try it themselves.
Here's a picture, following will be instructions:
Here's the how to: (Please read all instructions before attempting for a basic idea.)
1. Place the Dancing Flame vanity item down, or find someone that can.
2. Have /dance ready in a macro or just in your chat window and target the dancing flame.
3. Begin to mount your Sandstone Drake, Obsidian Nightwing, or any other transformation mount.
4. Right before you are finished casting (depending on your latency, it may take a few tries.) enter the /dance command while targeting the dancing flame.
To know if you were successful on your side of the client, during the process you will see yourself mount after completing the cast, then transform into a dancing flame, and then back to your mount form. If you wish to confirm, have a friend come watch and supervise.
Have fun turning heads!
