Nick S asked...
Is there any lore for the Trolls? I've seen very, very little that's not negative. Where's the Troll lovin'?!?
Unfortunately, I'm primarily Alliance and didn't see much from the Horde beyond the first couple of zones, so I'm not really sure about the Darkspear. Zul'Drak has a whole load of Troll content, though. It's an entire Troll zone centered on the last Troll Empire, the Drakkari. There's also the return of the Zandalar Trolls, who are much more friendly. You might have met them back when Zul'Gurub was run frequently. They're there to document the fall of the Drakkari and prevent them from doing something really, really bad.
The zone is actually very awesome, and coming from someone who was sick of Troll dungeons, Zul'drak pulled me right into the story. As you progress through the zone you see the Drakkari become more desperate, and as you get closer to the capital their depravity gets worse and worse. It's very well done. That picture up there isn't Zul'Drak, just in case you were wondering. It's Sholazar Basin.
As we're winding down on questions, I'm sure this has been covered (and I've missed it): do the 10-man and 25-man instances have separate raid IDs? For example, could I run a 25-man Naxx with the guild and turn right around and run the 10-man? Or, if you run one, are you stuck until they reset?
They do have separate raid IDs, so you most certainly can run both back to back.
If you champion for faction B and after you just championed for faction A, and faction A catches you wearing faction B's tabard, will you lose rep with faction A for "cheating" on them?
...No. Good deeds are good. The Argent Crusade won't mind that you smashed Scourge in the name of the Wyrmrest Accord.
I heard from a friend that Blues went back and said the championing would be allowed for old school reps (Timbermaw, AD, CC etc) in level 80 instances. How true is that, if it is? Or is it just like I've been reading for only Northrend factions?
As far as I know, it's not true at all. It's just Northrend factions. Knights of the Ebon Blade, Kirin Tor, Argent Crusade, and the Wyrmrest Accord. Maybe we'll see it in the future but I haven't heard anything like that since before Championing was even implemented.
Taking a cue from the starting zone quests questions, I am a lore freak, would it be possible (or feasible) to do the quests on BOTH starting Areas at some point?
Absolutely. If you're not worried about trucking along straight to Icecrown or whatever, you can certainly clear out Howling Fjord and then hop a turtle to the Borean Tundra or vice versa. Or you can go back at 80, or you can bring an alt over. Starting in the Tundra doesn't block you off from the Fjord at all.
Can you give us a short list on what instances there are in northrend, and at what approximately level you should attend to these? I don't want to miss any.
We'll have a nice, clean list for you before Wrath launches, more in-depth than I could give here. Keep an eye on the site!
