Pretty much anyone who is everyone should know by now that in WoW's earlier alpha builds (before the game launched), some of the capital cities were a bit larger and had additional levels or sections that were either taken out or made inaccessible prior to the game releasing. Blizzard didn't want to make cities "too confusing" to navigate and, in particular, made both Undercity and Ironforge a bit smaller by removing planned sections to the cities and their respective layouts.
So, I pose a question. Would you like it if Blizzard expanded Stormwind and Orgrimmar to be several times larger than they currently are and laid them out more like a complex, large city with multiple districts? For the sake of argument and dilemma, we'll assume the cities are both perfectly laid out so that no matter where you are in them, relevant points of interest (banks, auction houses, mail boxes, etc) are always pretty close nearby. Also pretend that they manage to expand the cities flawlessly without damaging any of the surrounding zones or areas the cities are in.
You can always opt to use one of the several smaller, unchanged capitols if you don't like how large Stormwind and Orgrimmar made. Essentially speaking, both cities would be terraformed and revamped to be roughly the size of a small zone and would be carefully laid out to feel more like a 'real' city. Also pretend that this wouldn't be an impossibly high tax on the WoW team that would result in them getting nothing else done.
So, would you, in hypothetical theory, think it would be cool if Stormwind and Orgrimmar were expanded into 'super cities' that were ridiculous and expansive in scale?
