Blizzard has already implemented elements of these. Regarding Omen, you get alerts around your unitframe when you're about to pull aggro. You get a yellow aura, and then it turns red when you actually pull threat. I think that's as far as Blizzard wants to go for having default threat meters. I somewhat suspect they don't want to put a chart or graph in front of all of their players with exact threat values and percentages. As much as raiders like Omen, that's not something Blizzard would put right in front of players. Leave it up to the mod authors.
There are also a lot of attacks that Blizzard broadcasts nowadays. No, they don't have the full DBM/BigWigs functionality... but I don't think a game company would ever give that to you either, the same as Omen. I think they've gone far enough with many bosses putting big bold yellow letters on your screen telling you what's about to happen. Have you done the new Coliseum 5-man instance? Eadric the Pure pretty much tells you exactly what to do and when to do it. Other than that, I think the stuff should stay to mods, and Blizzard probably feels the same.
"Do movement impairing affects also affect attack speed?"
The base mechanic? No. But there are select spells that do. If they do, their tooltip will specify.
"Are there any reliable Paladin blogs left?"
Depending on your spec? Sure. I'm going to do here what I did for the Rogue blogs: List your favorite Paladin blogs in the comments, folks! Personally, I'm Prot at heart, so I pay more attention to Righteous Defense and Honor's Code. I read a ton of Paladin blogs on a daily basis, but those two are my favorites at the moment.
"I've never played Warcraft III. Not even once. I was reading a bit about it on Wowwiki the other day and it seemed bursting with WoW-relevant lore. How much lore is going over the top of my head in WoW because of my dreadful RTS skillz?"
Quite a bit. Don't worry though, I suck at RTS games as well, and you can just do what I did. Use cheat codes. When you're in a level, hit enter, type "whosyourdaddy" and then hit enter again. Congratulations, you now have god mode and can experience the full story without worrying about getting shivved.
"With the 3.2 changes to resilience (covering all damage), do you think we might start seeing it being used as a possible tanking stat?"
No. Resilience only affects damage from players.
"Sooo... Did they take out the Get Kraken daily?"
No. Get Kraken! rotates with one or two other dailies, so you won't get it every day. You probably got something else in its place.
