You'll get some spill over rep gains from whenever you gain rep with another faction-city, so no need to do more quests to make the bars line up. They will eventually.
"How does a rogue poison his enemies using a mace, or a hammer? How does he apply poison to a mace in the first place?"
A lot of the time poisons are placed on weapons for a lasting effect, one that will end up killing the enemy no matter what the outcome of the immediate battle is. With a poison it'd only take one hit to kill someone, while a weapon would take several (on average). Rogues are no different in this regard, they just need to get the poison on their subject and let what happens happen.
And with this question, it's my chance to use this image of Sting, who carried poison tipped daggers in Dune. Watch for more Sting tomorrow morning.
"Do instance portals work if you don't jump?"
"Are any wow.com columnists going to PAXEast?"
I know that Sacco is going, and since I'm on notice here's his phone number: 555-632-9127. But he's the only WoW.com person that'll be there, I think. Joystiq, our sister site, will have a crew out there, and they'll be rocking the place with the best coverage on the net (for real, their event coverage is amazing).
"When WOTLK went live Wow.com posted starting zone upgrades for each class. Will we get another starting zone upgrade when Cataclysm goes live? If so will there be a more detailed guide covering the different zones or it will focus on just one zone?"
We have a ton of content planned for Cataclysm, and a ton of great staff to do it. There are several of us who are going to be doing nothing other than focusing on Cataclysm guides soon, and starting zones are on the list. Some of the highlights: videos (tons), strategy guides (for everything), talent guides, glyph guides, zone guides (including pictures and videos, before and after Cataclysm), and hopefully some live dungeon running when the beta is up. We'll probably use something other than Ustream as well, so we can get you guys a really good picture.
