Wings/Scarves/Capes ect. Using different kinds of back accessories as a ‘mount’ for your character to be able to fly around like an Evoker does.
This could even be extended to ground mounts eg skates, backpack with extended metal legs. Fun ideas like this…
Was in Aion, didn’t save it from falling into obscurity.
I’m kinda surprised we still don’t have a jetpack mount tbh
No no and no, absolutely not!!!
How dare you suggest something that could be loads of fun and cool? Jetpacks? Pff! The mockery towards the devs. How would you think they got time for anything other then recolours? 
Shame on you for such a good suggestion.
