With patch 4.0.1 you are able to "ignore" phasing.
This means for example: you are able to do the battle for Undercity again, while also being able to see all vendors in Undercity, too!
1. All you need is wintergrasp to be controlled by your faction, so you need this buff:
Essence of Wintergrasp - Spell - World of Warcraft
2. Fly over wintergrasp, once you entered it, leave the battleground, by clicking on
the button on the minimap, which looks like the icon of your faction
Horde: http://images3.wikia.nocookie.net/__...8/Horde_15.gif
Alliance: http://images4.wikia.nocookie.net/__...lliance_15.gif
3. Now you'll probaly notice you've got the buff 2 times.
It's done, now you're able to see for example the battle for Undercity, again.
This buff lasts as long as you want it to last, you can walk around in Orgrimmar, while still having it. Also you're able to kill the Elementals, which have a guaranteed droprate of 1 element and as many as 3 elements, like this one: Earthbound Revenant - NPC - World of Warcraft at any time, even if your faction is not in control of Wintergrasp!
Important note: to remove this "bug", simply enter a battleground or wintergrasp.
To prove it worked, I tried to make some screenshots, which show 2 events occuring at the same time:
