Hope you have a mage

Out of curiosity...

How much of the city is self contained districts, like the current city.
When in the Trade District, you cannot see Old Town, Dwarf Quarter or the Mage Area.
So even if those were all very high polygon counts, they wouldn't strain your system at all.

How much of the city is vast open space, like Shatt/Dalaran?

There are no extra large spaces BUT I think it depends on how the designers grouped the area. It did feel a little more sluggish than live although this is most likely due to bein gon a Dev server and not live.
