Still waiting.
Someone did the work to create four color variations, but only one was added. Why waste asssets like that?
Here is a picture of all four: https://www.reddit.com/r/wow/comments/b1fwqx/the_kul_tiran_flight_form_doesnt_change_colors/
Here is a YouTube video from the BfA beta with all four: https://www.youtube.com/watch?v=2r6LIRRCWf4
This is ridiculous that these are still missing from the game. Dozens, probably hundreds, of posts have been over the past three years in the bug report, general discussion, and druid forums. We’ve been completely ignored. All while new druid forms are added.
We aren’t even asking for any new forms though. The work has already been done! Just add the missing files to the game and/or fix whatever bug is preventing us from using these beautiful assests that somebody put the time into making.
