So... Blizzard decided to remove a major chunk of the attunement process from the raiding game. For those who don't know there were major attunement quest series:
Karazhan: First do two quests outside Karazhan, followed by some fed-ex quests. Then you do Shadow Labs, followed by Steam Vault and the Arcatraz for three key shards. Once the key shards are combined you go do the Black Morass and talk to Medivh after you complete it and that will pretty much get you keyed for Karazhan.
Gruul's Lair & Magtheridon's Lair: No keying needed. Just mentioning it to be complete.
Serpentshrine Cavern: First get Revered with Cenarion Expedition. Next do about half of Heroic Slave Pens to find a slave shortly after the first boss. Talk to him and he'll give the attunement quest. Now, go kill Nightbane in Karazhan and Gruul in Gruul's Lair. They will drop items for you. Go back to the guy in Heroic Slave Pens (still after the first boss), and you can get in.
The Eye (Tempest Keep): First, do this entire questline: http://www.wowhead.com/?quest=10680 which is one of the longest in the game... something like 10-12 steps. It's bad, but worth it if you're not raiding already (some nice rewards at the end). Once you complete that questline, then go to Shattrath, to recieve three quests... now go get revered with Honor Hold/Thrallmar, Lower City, and Sha'tar (should already be revered with CE for SSC) and do Heroic Steam Vault, Shadow Labs, Arcatraz, and Shattered Halls. After that, now go kill Magtheridon.
Battle of Mount Hyjal: Talk to Soridormi in Caverns of Time. Now go kill Vashj and Kael'thas for their Vial Remnant (water from the Well of Eternity). While it's easy in writing you still need to be able to beat both of the two previous raids. But you should be doing that before you go into Hyjal anyway.
Black Temple: First a questline from either the Aldor or the Scryer base in ShadowMoon Valley, that has you investigate the Ashtongue Deathsworn. This ends with you meeting Akama, and going to the Arcatraz to find a corpse there. From there you do a few more quests in SMV. It seems to end there, but it picks up in SSC where you meet Seer Olum after beating Fathom-Lord Karathress, who starts a long questline that has you kill Al'ar (first boss in The Eye) in a Broken costume, followed by beating Rage Winterchill (first boss in Mt. Hyjal). A few more quests and you're in (there are also a few quests after you enter).
Now, they've removed the SSC and TK portions, which I think was a very smart move. While yes, a lot of the rest of the attunements have you doing tons of stuff, those two attunements are the only ones that require doing Heroics, which is where I think Blizzard went wrong. The problem is that that heroic keys require being revered with the matching faction. This means to progress into SSC you need be revered with CE, and beyond that, you need to be revered with HH/Thrallmar, Lower City, and Sha'tar as well. It's just insane. I have no problem doing long questlines or going back and doing a run or two through a 5-man, but forcing the entire raid group to repeatedly do 5-mans for rep just so you can do another even harder 5-man (heroic) is way overboard. I wouldn't mind if they had just changed the SSC and TK attunement questlines to remove the Heroic parts, but this works as well. And they've left the questlines in for those who want to do them.
Addendum to this post: I'm very happy with this change. I had been having nightmares about the portion of attunement that was removed. As I said in a post below, my guildies hate doing PUGs, and to be honest, I know of at least 3 people who are not, and would not without a lot of guild runs (thus a long wait), become revered with the factions needed for SSC and TK raids. Doing a quest chain, even a long one? Fine! Having to go back and do an old 5-man? Fine! Needing to get certain people through Karazhan again for some item? Fine! But requiring people to be revered with all those factions, esp. 35+ people (the minimum you really need to be able to raid a 25 man instance without having people being gone cripple the raid) would have been a logistical nightmare.
Getting over idleness - If I look at my Steam account, the game I played the most is Idle Champions of the Forgotten Realms with 1400 hours, way ahead of XCOM 2 with just over 200...
