Viewing the results of the poll, each day people surprise me more... why the hell we need a Gilnean district in Stormwind?
I know that Gilnean architecture is cool, but honestly, it would look out of place with the rest of the city, and above all: the kingdom of Gilneas has its own capital and its own peninsula! (though in WoW only appears half of the peninsula) Gilneas does not need any district in Stormwind! It is as if in Orgrimmar was established a district with Forsaken architecture...
Besides other hand, Gilneas has always been a very introverted and not expansionist kingdom, so its representation in the rest of Azeroth should logically be very little.
As I said
here, I would bet that the old park of Stormwind was rebuilt to accommodate an important segment of the Alliance who currently have neither capital nor any city since they are in exile.
I refer of course to the Quel'dorei, which are a fundamental part of the Alliance, those who despite this have barely received their corresponding tribute and homage.
In fact, I would create an Elven District, especially dedicated to the high elves but also to other elven races as night elves or half elves, and even also will have room for other races that have special relations with the elves, as worgen or draenei.
