I always want an air combat in Guild wars2 since the beginning, but if it’s possible? I think yes!
Sorry about my English but I will try my best to express my thoughts.
The underwater environment has already proved that Guild Wars 2 is fully capable of handling 3-dimensional combat, just imagine replacing the water with cloud, kraits and barracudas with harpies, this is going to work.
Anet can first try to make an air combat PVP map with this concept. Players spawn in airships and wearing jet packs designed by Charr or Asura, then fly out of the ship players will instantly enter the battlefiled.
Or Anet can make a mission with this concept, just like some underwater mission.
Well that’s all I could think of, thanks for reading : )
