I think it would be nice if we could see dragons flying in the sky all over Tyria, in every zone not only in Orr.
I imagine it like this:
They take a random number of dragons from 1 to 10 and they will randomize their spawn in every zone on a time basis: when dragons leave one zone they will appear in the next zone where they were headed to.
Lets say, 7 dragons will fly over one zone for 15 min than 5 leave in one direction, 2 in another. In those 2 zones there will be flying dragons for another 15 min.
From here, the dragons can fly all to a single zone or spread out again.
Anyway, there will always be 3-4 zones with dragons flying in the skye
We DON’T fight them, they are only in the sky, flying over in different numbers and different altitudes.
From time to time they will breath minions and poison on the ground but not as an event only as a spawn-able mobs fitting with the zone level.
Also, the dragons will make specific scary noises so every player, new or old will get a chill from it.
I think would make a real impact on how the players see the world and the threat the dragons actually are
(Note: I got this Idea after seeing the Holographic dragon over Lion’s Arch at the Dragon Bash Festival, but the dragons I am talking in my suggestion are smaller ones and fly in packs and they look like real dragons not a holographic image)
