Is Hunger For Blood, the 51 point Assassination talent, at all useful for solo leveling?
I asked a friend of mine about this since I don't personally play a Rogue, and he says popular opinion is that Hunger for Blood is mostly going to be a PvP talent. Keeping the damage buff up constantly while questing isn't worthwhile, and the debuff clearing it provides will be highly situational while soloing through Northrend. You can take it if you're gung ho about Assassination, but you'd be better served picking up something else until you start PvPing often.
Are there or will there be any Aldor vs. Scryer type factions?
Yes, though it doesn't play as large of a role as far as the main story goes. Within the Sholazar Basin you encounter two factions: The Oracles, a group sentient gorlocs, and the Frenzyheart Tribe, a group of sentient wolvar. Wolvar being overgrown badgers or puppies or something. No, I'm kidding, they're supposed to be wolverine people (not worgen/werewolves as some had said). There's a very real conflict between the two factions, but it's very lighthearted. Both factions talk a bit like lolcats so it's hard to take them too seriously, despite the fact that they're in a horrible bloody territory war in which you summon their various gods and deities to slaughter the other side en masse... but I digress.
These two factions is another massive example of how much better Blizzard has done with storytelling via quests in Wrath of the Lich King compared to Classic and BC. These two factions are far more whimsical than the Aldor and the Scryers, but the quests set up the conflict pretty well. The conflict remains a bit silly, but the story is at least set up for you from the beginning, rather than you being shoved into Shattrath and told "Pick one, go go go hurry go go!"
Dalaran has two opposing factions within it as well, but one is Horde and one is Aliance, so you won't get to choose or switch or any of that.
Will any other cities besides Undercity, Orgrimmar, Stormwind and Ironforge be getting any love? Or are they just as worthless as they were in BC?
As far as I know, the other capital cities aren't getting any major changes, though I would disagree that Silvermoon City didn't get any love during The Burning Crusade's lifetime. That city probably went through more story-related changes than any other capital until Stormwind Harbor. Back to the point though, as far as I've seen, the other capitals remain static. However, you will indirectly learn more about Teldrassil, which isn't a change to the city of Darnassus itself but opens up possibilities for the future. Awesome ones.
Maybe this has been brought up before, but I can't help but wonder, do all players receieve an inscription page to use inscriptions or is it Inscriber only?
All players receive a page in their spellbook in which they can use glyphs. Everyone is able to use 3 major glyphs and 3 minor glyphs. Scribes (inscriptioneritors) get an extra Major glyph as their tradeskill bonus, sort of how Enchanters get ring enchants and Smiths get to add sockets to certain slots.
Glyph of Renew - Reduces the duration of your Renew by 3 sec. but increases the amount healed each tick by 40%.
Glyph of Flash Heal - Reduces the mana cost of your Flash Heal by 10%.
And that's all for today, everyone. If you have additional questions, please ask them in the comments section below to be answered in a future edition!
