It's probably not that big of a deal, but its something fun.
Well I was in AV and while we were killing the Van, I had a used the skill "Storm, Earth, and Fire" after he had died I respawned in town, but I remained in the storm form. I tried logging out and switching characters (haven't left town yet), but Im still in the storm form, so I decided to have some fun and mount up and make it look like I had different spectral mounts.
If you like how they look, just pop into a bg and have one out before it ends
