Any new storylines for the Draenei?
I haven't seen any major representation for them throughout Northrend, no massive plots just focusing on them, but they do have a presence and they are right there alongside the Alliance and the Argent Crusade. In some of the early quests, you do some unraveling of a cultist plot, and it's the Draenei fueling the investigation. Apparently thousands of years of the Legion trying to infiltrate your ranks makes you pretty good at sniffing out spies. A lot of their quests are that sort of thing, lending support to the Alliance rather than leading the charge like they did in Outland.
There are a few other quests that show that the Draenei are starting to grow accustomed to Azeroth, and are settling into a calmer life there. They're not fleeing exiles anymore. Azeroth is home to a lot of them these days, so they'll fight Azeroth's fight, and some of them just plain want to live life. Explore and go on whimsical adventures like the rest of us.
Are Prot Paladins having less downtime now with the buff to Blessing of Sanctuary?
Most definitely. The effect on Blessing of Sanctuary is incredible, and makes Protection Paladins even more powerful at AOE grinding, though I haven't found many spots to do that yet since the 'end game' zones are not currently open. There's bound to be a fantastic Undead-grinding location in Icecrown, but we can't get there yet. Downtime in 5-man dungeons is dramatically better as well, it vastly helps 'mana starvation' from being overgeared for a dungeon. You won't need to get half naked to tank something below your gear level anymore, thankfully. For those of you not familiar with the updated Blessing of Sanctuary, and since the Wowhead link lacks the most recent version of the ability, here's the spell description:
"Places a Blessing on the friendly target, reducing damage taken from all sources by 3% for 10 min. In addition, when the target blocks, parries, or dodges a melee attack the target will gain 10 rage, 20 runic power, or 2% of maximum mana. Players may only have one Blessing on them per Paladin at any one time."
It's an amazing tank blessing now, for all of the tanking classes.
I can haz rep?
No rep for you!
Everyone that has ever existed asked a bunch of glyph questions, so I'll try to give a rundown.
As I said yesterday, you can use 3 Major and 3 Minor glyphs. If you are a Scribe you get an extra glyph slot. You can only use one of each individual glyph, so you can't use three Glyphs of Renew, for example. To slot a new glyph, you must destroy the old one, just like gems. You cannot remove them without destroying them. You cannot change them without destroying them. You probably can't put a Minor Glyph in a Major Glyph slot but we don't know this for sure, since zero Minor Glyphs have been implemented as far as we know. Glyphs are used via purchasing the physical glyph from a Scribe, right clicking on it, then clicking an empty circle on your glyph pane. Yes, Scribes can put glyphs on the auction house. If you missed yesterday's Ask a Beta Tester and didn't see the picture of the page in your spellbook, here it is again. The large circles are for Major glyphs, the smaller ones are minor.
Is Hammer of Righteousness a spammable ability?
It has a 6 second cooldown, so you can't tank just by smashing your face on your Hammer of the Righteous button. You'll be using it regularly in a rotation with your other tanking abilities, but you won't be using it exclusively.
Is Honor going to be reset or just arena points?
I do not believe we have been given a definitive answer on this, but Honor wasn't reset with the release of The Burning Crusade. I don't imagine it would be reset with Wrath of the Lich King. If that changes, we'll keep you updated.
If I already have a title and I qualify for a retroactive title via achievements, or gain a new title later, do I get a choice on which to keep? Can I later swap to the one I want the most?
Gaining a new title doesn't get rid of an old one, unless it's something like Arena titles which only last for an arena season. All titles that you earn are added to a dropdown menu. You can see an example from my current title pane below. I fail at getting retroactive titles on my main apparently, but it shows off the menu decently enough. You can only choose one at a time.
